What role do users, developers, and miners play in resolving forks and hard forks, and what are some best practices for handling these situations?
do you think that the innovation of new coins will improve the overall quality of the cryptocurrency ecosystem?
Soft Forks are like an update you receive of your app that promises you new features, yeah, an example of that is SegWit protocol integration, Taproot upgrade. You can keep your old wallet outdated, that means saying no to soft forks.
Hard fork is like to download a completely new app that's based on your original app. Bitcoin Cash is an example of hard fork. In case of Bitcoin Cash, there was a proposal to significantly increase block size but this idea didn't gain the support of miners, node runners and bitcoin business owners. In case it had 100% confirm, then we all would change the chain and continue mining of new block lines and it wouldn't even be called hard fork. But since a lot of people didn't support the new idea but some still continued to support, there were a group of people who forked the chain and continued mining of these new blocks. Finally, that's how BCH was created but it doesn't mean that this coin is better than Bitcoin, there are many reasons behind this.
New fork can improve the quality of cryptocurrency ecosystem or can turn into another junkie, both are possible.
