And we can't do anything about it really. Governments are greedy, they want a share of everything and therefore thy will be trying to snatch some of it from us.
There is a really high chance that we see in the future a lot more government action against bitcoin, including some changes of the core protocol.
Another case is that I think bitcoin is "too good" now for people. So Bitcoin will be changed to bring it in line with other payment systems.
We probably will se some dreadful changes like adding possibility to blacklist funds and and change that will allow to store identity information of users with bitcoin transaction.
Your thoughts?
