Bitcoin's an expensive jewel leaders want to get or control. It's about power. When bitcoin's were traded p2p it was different but after countries made plans to make bitcoin reserves it's become something Satoshi wouldn't have liked. There isn't a guarantee bitcoin's going to get faster & better because if countries can't control it they'll ban it to reduce it's influence on ppl.
There are always two sides including Bitcoin. People who don't like or believe then they are likely to make bad opinions about Bitcoin. Likewise the other way around. So far in history it has been repeated, so some bad predictions about Bitcoin's future should not have happened. As the industry grows bigger and faster, I think Bitcoin will get better. But Bitcoin technology because of its fotalicity and anonymity is still being researched by many countries. So far it feels good, there is still great hope, crypto can become one of the world's recognized financial systems. But we have to remember the bad chances, Bitcoin can get better and it can even get worse. We don't know the future, prepare our best plan.
