Any chance you have a firewall, modem or ISP that's blocking connections? That's normal, especially when you're low on RAM. I counted several TB read/writes in total just to sync Bitcoin Core with 8 GB RAM.

This got me thinking, and correct me if I'm wrong: someone with enough ASIC power could not just do a 51% attack, they could build a completely new chain for testnet 4 from the very first block! There are currently…

According to ASICMinerValue.com, this thing mines €18.53 worth of Bitcoin per day. So the cost (in missed revenue) of this 51% attack to anyone who owns this ASIC would only be $21 per day. I'd say the fact that nobody…

Testnet's hashrate is closer to 0.0001% of mainnet, right? It's really low. If I understand correctly, this would be possible with much less than 51%: I think this should work: wait for a block storm. Wait for hundreds…

Testnet isn't meant to "build on". What makes you think it's ckpool that's doing this? You may want to read Testnet4 Mining (Discussion) (to start): I've seen some discussion about how to improve testnet, but all…

This doesn't mean much: I think it's only based on sending the full amount. The sending fee is only 1.01 sat/vbyte, making it unlikely to be stolen. A thief would likely use a higher fee. I've never used "Trust" wallet,…

I'm going to disagree with you the guy you copied this from on many points: This doesn't mean anything if you don't use a wallet on your node. My full node only used a few percent of it's allowed bandwidth. That makes…

Did you start it from console? If not, try it: leave the console open to see if it outputs anything there when it closes.

You can change Bitcoin Core's port, but they'll probably block a lot more ports. Is your mobile provider okay with that much data?

Isn't a pruned node much easier for your purpose? You'll only need about 15 GB of disk space, and it still verifies every transaction you make. The only thing it can't do, is sync older wallets or load older keys. I…

Bitcoin Core still works totally fine, and I haven't tried Knots. But if you're still have a nomadic lifestyle without permanent internet, Electrum is much easier. I run my public Electrum server using Fulcrum on top of…

I assume you're talking about Electrum, and I have good news for you: those 30 different Bitcoin addresses are all yours! You may want to read up on why to "avoid address reuse" (TL;DR: it's good for privacy and keeping…

They may block your account. Coinbase for instance is well-known for blocking accounts if users send coins to an online casino. It's safe to assume centralized exchanges are analysing incoming and outcoing coins.

Let's see: Here, the high rates starts at owning just €50,000. That's "wealth", according to government, and needs to be punished. If you'd own €10 million here, you'd have ways to legally get away from paying those…

Maybe I'm naive, but I always assumed the majority of Bitcoin users doesn't do it to evade taxes. There's one very simple reason: if your small Bitcoin investment turns into a small fortune, you want to be able to tell…

Before answering this: who are you trying to hide from? It makes a lot of difference if you're trying to hide from your wife, your government, or random people on the internet.

That's not possible. But you can send Bitcoins to for instance a Forkcoin address, and it will be very difficult (or impossible) to get your money back if you deposit to an exchange on the wrong chain. Correct. You have…

I'm Dutch, and Kraken works for me. Germany is close enough so I expect it to be allowed.

I don't know the site. Maybe this German topic helps you.
