So, it is already here. it was to be expected. the market do not want a fork and it shows it with a big fall and the market will be in this mood until the situation clears out. The fork will be imposed anyway because...reasons. pick the one you like. Your prefered excuse won't change the situation we are to face until mid August.
Now, the question, looking forward is, will the bitcoin participants learn something from this? is there any change to be expected on how bitcoin will develop in the future? is a change even desirable?
my impression is that as it is, bitcoin governance is better than free beer for propagandists and I do not see why this would change any time soon. Reason is dead.
One thing that I have already learned, is that there are a lot of idiotic people out there selling their Bitcoin because they are in a state of panic. I can understand that a lot of people would be scared when they hear things like "a fork is going to happen", "there will be some kind of split", but the fact that they aren't bothered to research it and actually realize that it will be good for Bitcoin if the block limit increases.
However, this was already expected from a long ways away. There are always going to be people like this in the world, people who are dumb enough to just sell things without fully knowing what is actually happening. I hope that people learn their lesson from this and if anything big ever happens to Bitcoin again, and there probably will be, hopefully they will be a bit smarter with their decision making.
