Right now bitcoin is a very dangerous investment, it's at the top of a hype now.[citation needed] There's notging backing bitcoin, and i'm not talking about value backing with tangible assets, I'm talking about the community and developers ignoring fundamental problems with the system.
We can save bitcoin only if we want to offer ourselves and the world a solution and not think of our personal greed for a moment.
i agree with the part about blocksize needing urgent improvement (I believe this is being worked on, but SegWit was supposed to go online in April, so they're quite late, but the positive side is that it probably won't take much longer. I also believe a 2MB upgrade is agreed by the miners, but I don't know when and how that will happen.
