Banks are embracing blockchain and will do everything in their power to reign it back in under their control. Just look at Ripple.
Bitcoin was suppose to be a new form of money, independent of any government or bank. Unfortunately, some people are desperately trying to tie the legacy banking system to it via an ETF, Ripple coin or anything they can put the word 'blockchain' in front of.
Predicting the future is tough, but you're correct that regulation is coming. I can't say that the bitcoin price will never crash or be gamed, but since it has no CEO, no President, no board of directors, you can't bomb it or place sanctions on it, I will just have to trust it. As more people continue to use it and flee the fiat paper system, I believe it won't go away anytime soon. Add to the fact that there will only be 21 million created means it can't be deflated away either. That's why I prefer it to keeping cash in a bank. Bank gives you no interest and it can be taken from you at any time.
No government can steal my bitcoin unless they have some mind reading machine that I'm not aware of.
Take care @valued-customer
