Is it true that you should sell bitcoin when altcoins start to rise?

A while back, I caught a video on YouTube where a trader talked about selling bitcoin when altcoins begin to surge. Anyone know who that YouTuber might be? I can’t recall the exact details from the video. The gist was that significant altcoin rallies usually indicate we’re in the late stages of a bitcoin surge, and that it’s a sign to cash out on bitcoin before a correction happens. I’d like to know if there’s any validity to this since I don’t really follow altcoins and think they’re mostly worthless. Hearing that they’re gaining value and seeing polls where bitcoin isn’t even the top choice gets me concerned. Like, check out this poll on Stocktwits with 16,000 votes: Which crypto is the best buy right now? Bitcoin 20% Ethereum 25% Solana 10% XRP 45% 16.4k votes People are seriously favoring XRP and Ethereum over bitcoin now. This feels significant, especially when you look at historical bitcoin trends alongside what that YouTuber said about selling when altcoins rally. I’ve been hearing way more about altcoins these days compared to bitcoin. Just feeling a bit uneasy about it all. I remember back when bitcoin hit $1,000, and shortly after that, altcoins went wild with ridiculous valuations, then everything crashed.

Bitcoin doesn't follow altcoins, but altcoins follow Bitcoin. Different people with different theories, just be careful. If you want to mislead yourself, follow those YouTubers, they will easily mislead you.

Honestly, that viewpoint feels kinda stuck in the past. The crypto scene in 2025 is a whole different beast compared to the days when Bitcoin barely scraped past a thousand bucks. We got all these new narratives now. And the relationship between Bitcoin and altcoins? Way more complicated than it used to be. Sometimes Bitcoin is the star, sometimes altcoins steal the show, and other times, they are just vibing on their own wavelengths. Its not as black-and-white as it used to be, I think.

The past experience for me is that's the best time buy bitcoin actually. When altcoins climb up - invest in bitcoin - wash and repeat

I find this kind of polls somehow because all of a sudden people are now saying buying of Ethereum which has always been down for some period of time as the best asset to buy, I could remember when bitcoin was approaching the price of $100k many were calling for others to invest into Altcoins as that will be the best time for Altcoin rally to begin, but after few months all of these Altcoins are went almost 50% down with Ethereum yet to see any ATH since 2021. Bitcoin at every period of time is the best asset to buy, buying another coin is simply gambling because you don’t know maybe they will even go up or not but with bitcoin there is the historical data to back it up that bitcoin will pump. For me I think one shouldn’t be taking anything from this social media any seriously most especially if it concerns investment

It's more of seeking for additional profit. Altcoin season usually happens once bitcoin is having a big rally. To maximize profit at time like this you need to rotate your profit from bitcoin to altcoin before it's going up. It could be true to some extent but just because altcoin season happens in previous cycle doesn't mean it will happen right after bitcoin bullrun again. More of a bet in my opinion where you're betting the bitcoin dominance to dump so sharp and altcoin price increase.

You can only maximize profit using this method if you can have a perfect timing for your buy and sell the right altcoin. Not altcoin behaves the same with Bitcoin so you might buying a  shticoin that doesn’t move or rally greater percentage than holding Bitcoin growth itself. The best time to sell Bitcoin is when it reach new ATH and do it in tranches.

I'm not sure if that holds, I mean we have seen Bitcoin decoupled from Altcoins this bull cycle already. But before that was the pattern, but when Bitcoin hit's all time high pre-halving, it was a different pattern distinct from the supposedly altcoin follows Bitcoin narrative. Exactly, for all we know, influencers will tell everything, but behind all of it, they don't have the experience or even losing more. And so they will just shill any altcoins because they might be holding a lot of them. So I wouldn't listen on Youtubers, specially very young.

People are picking XRP is because there are wo many investment comoany filing ETFs which they allocate at least small percentage for XRP token. I saw a news just yesterday that Trump Family company is also filing XRP ETF along with other altcoinw wuch as SOL and ETH. FOMO  must be coming soon as altcoins are shooting but I dont think its time to sell BTC. Keep holding if youre not buying.

Sometimes, we may not have to look at the present performance of a coin, but the long term effect and implication upon any decision we make, that is why in choosing between which coin to go for, we are not expected to go by the hypes created, instead the way they have been of a value to the general world and how they can serves a long and lifetime utility value, its a shame that some are still seeing other cryptocurrency having prospects than what bitcoin stand to give, when some of them may fail to perform for a long, time, now we are in the bitcoin season, i don't expect any other decision other than bitcoin.

It seems that the speculation that Youtuber was specified in 2017, but now the era of 2025 is different from before, but if YouTuber is guided by 17 of course yes, it could be true what he said. We have experienced twice Halving Altcoin there is no change, precisely when Bitcoin rides Altcoin plummeted, how do we guideline the speculation of Altcoin rose, so now the guidelines on Bitcoin itself, where users are sure to sell of course do and do it and Not sure to hold, remember the current atmosphere has changed, investors only focus on Bitcoin, Altcoin as a means for market crowds, not a benchmark.

We need to understand the context first. @OP said it's a Youtuber who trade Bitcoin, so we need to highlight trader, of course trader only care about the short term gain. if we talk about trading, it's correct because when altcoins rally, it's not Bitcoin price will dump, but you will miss the big gain in altcoins. So, most likely he advise to sell Bitcoin and immediately buy altcoins because he think altcoins season will happen.

In the past the way it worked was as follows. Bitcoin pumps, then it seems to stall while altcoins seem to pump and then eventually they both top out. What happens is the whales pump bitcoin first and while people are piling into bitcoin they get out and move into altcoins and then they pump the altcoins. So later altcoins rally and typically the whales move into stablecoins and then the market peaks. This might repeat but there is no gaurantee.

Some of us still believe in such a scenario, which is why they buy more altcoins than Bitcoin. An altcoin season is expected to arrive when Bitcoin investors shift to altcoin, but you're right that such a scenario is never guaranteed to occur during this bull season. Of course we can utilize both (bitcoin and altcoin) to get bigger returns, but especially for long term investment then I would still suggest them to hold bitcoin instead of altcoin. Many of us expect short-term gains from altcoin, while long-term gains from Bitcoin. I own both assets and they've both yielded returns so far, but I'll definitely hold Bitcoin longer for a larger purpose. Altcoins are not for the long term, although I have some of them in my investment portfolio so far.

He could be right because that's what he thinks about the market. Everyone is free to say what they think about how Bitcoin will do next. Before an altcoin season, Bitcoin is the first one to pump and that's the reason why many altcoin holders are hopeful when they've seen Bitcoin rally. But here is a reminder, whether right or wrong, don't believe quickly what you see from these content creators and don't make them involved in your decision making.

I can't remember a video that I watched saying that, but based on what you shared, that YouTuber is saying that the altcoin season might start anytime. What investors do is that, when they feel that Bitcoin has already peaked, they will sell their Bitcoins, and that lowers the Bitcoin Dominance (it's happening currently), then after that, they will try and put it into altcoins to gain more profit since altcoins tend to move a little bit late compared to Bitcoin, and it's because of this reason. For me, altcoins are also a good investment provided that you focuses more on the top ones, and that's why we see top altcoins exploding. Investors transfer their money from Bitcoin to altcoins. Hearing more about altcoins than Bitcoin doesn't mean trouble, and you're just saying that probably because you're focusing more on Bitcoin that you forgot those altcoins already. There's nothing wrong with that though. What I'm saying is that, there's also an opportunity in altcoins, and not only in Bitcoin. 45% on XRP? Maybe it's because there are many who believe that XRP has more upside than the other 3 coins hence, the more votes, or maybe because many believe that a Spot XRP ETF will happen soon. Anyway, this YouTuber that you said can be right or wrong, but don't blindly follow what he said. Focus still on your convictions. Focus on what the chart is saying.

Both bitcoin and altcoins have varying potential returns - but if you want to be safe, bitcoin is the best choice. You don't have to follow anyone else's standards when investing - meaning you can independently plan and make decisions for your own long-term goals. Bitcoin is believed to be more than just an investment asset - of course, its real use case as a means of payment is what differentiates it from altcoins. The choice is theirs - in reality, bitcoin is still better in the long term. You can capitalize on the up trend momentum of altcoin prices - but be careful, you can also get caught in massive price spikes and massive price drops.

That's right, it's important to study market movements yourself so you don't hesitate to make decisions. Others may be speaking out of self interest. Bitcoin will continue to dominate the market. Anyone can see the cyclical nature of its price movements from year to year, and altcoin seasons are often only temporary. Those who understand the market may be able to profit in the short term, but Bitcoin is guaranteed to consistently provide long term returns. Bitcoin is currently experiencing a slight correction, but it's not far from its all time high, and I don't think the altcoin season has yet begun. However, this may not be the right time to accumulate, as altcoin prices have risen significantly alongside Bitcoin price. On the other hand, many believe this is still the early stages of a bull run, and it may peak when Bitcoin reaches $130K or even more.

While many don't believe in altcoin season, it is indeed happening as ETH is approaching its 2021 ATH and has tripled from its lowest bottom since 2024. Bitcoin dominance is dropping significantly and the money flowing into altcoins is real but for the altcoin season to really explode, altcoins increase x5-x10. Bitcoin needs to continue to grow to attract more money from outside, so there is nothing wrong with continuing to hold bitcoin. In short, whether or not to sell Bitcoin now will depend on each person's investment strategy. We should analyze and make our own decisions because no one can guarantee anything to each other, the future is unpredictable. Bitcoin maximalists, as well as those who don't invest in altcoins, certainly don't like this, but the truth is that altcoin season is approaching.

Bitcoin is the best coin to buy in all seasons be it in the bull run or bear market. Don't be deceived by traders who are after quick profits and is always on the watch for which shitcoin that will pump. We might not see an altseason this time around because bitcoin is still pulling the waves while shitcoins are only watching. The altcoins are on a little pump but that doesn't mean that they would continue to pump, because a little dip in bitcoin price, might be a drastic dip for them.
