Long-term hurdles facing Bitcoin

A lot of the conversations here tend to zoom in on bitcoin's price regulation and energy use, but there are actually a bunch of technical and economic issues that don't get as much airtime. I wanted to bring up this topic to highlight these challenges and see how everyone feels about them and if there are potential solutions. - Long-term security budget: As block rewards get cut every four years, miners will depend more on transaction fees. Sounds fine in theory, but the big question is will those transaction fees be enough to keep miners interested in securing the network? Plus, there’s a chance that hash power might drop, which would make attacks more feasible. How do we tackle this? People aren't talking about these issues much now since they’re not pressing, but they could become major headaches in the future based on the protocol choices we make today. - Growing UTXO set: Bitcoin nodes keep track of all UTXOs because transactions depend on them. With the UTXO set getting bigger, the storage requirements for a node are going up too, and that could deter individuals from running full nodes. If fewer people are doing that, we’ll end up relying heavily on institutional nodes, which could hurt decentralization. This is definitely something worth worrying about.

Yes you’re right the major discussions on the forum is mainly about price and that’s because many people into bitcoin are in for the profit side only. But the two discussions you also brought have been discussed here multiple times. This particular discussion is one of the most widely discussed technical questions even on this forum. This particular question remains unanswered because the period before the block subsidy stops coming is still far from today although in the next few years like 20 years from now block reward will be around 0.048 which is definitely low and since we will know whether we the fees will be enough incentives for the miners and if not something will change because we have seen forks for bitcoin best practices in the recent years. But for me I think fees will be enough if the market price of bitcoin continues to increase and also the more adoption it gets the more people use it for transactions and therefore more fees most especially if it’s starts to get accept by business then even second layer networks to can come in This has actually been a concern and has also been discussed freely here, for some people who don’t have space they can simply try pruning which is run a prune node for space more space. why I don’t worry much about space is because technology is growing in the past a 1GB data or file was a big one because of lack of storage means but today we have even phones with TB for storage. So I think technically advancement will help solve this one and shouldn’t be a worry at all

Maybe you're not active in the technical board all this while. Concerning this, you should check out my thread Can Bitcoin survive on fees alone after block subsidy dies? several users addressed this issue under that post. I believe there are other threads too but mine is the most recent I think. On this one, you should check this thread ‎The Data Bloat Dilemma: Is BIP-110 the End of Bitcoin as Digital Gold? I believe related issues were discussed there. You may find some helpful information on those threads. Remember you're in Bitcointalk forum. If you really think these issues are under discussed, you are probably not visiting the right board.

I haven't seen such topics you just mentioned in a long while People barely talk about energy consumption and price regulation? Uhh I'm too lazy to start showing threads about these. Like I usually say if Bitcoin is doing fine before all rewards stops It would after. We have difficulty adjustment And even if it becomes relatively cheap doesn't mean a double spend would be viable. adding to what Zaguru stated Storage isn't expensive And it gets cheaper as years and technology development increases We can associate it to Moore's or just plain old technological deflation.
