You can bet everything that the big banks will dig their claws into crytocurrency, they're already strategically working on their own ICOs (Goldman Sachs).
If corrupt establishment firms like Goldman get involved, you know they will lobby and payoff to regulate other coins. Here in the USA it is nearly impossible to buy cryptos with USD. I can't stand it!
The US is very protective of its dollar, there is too much money to let anyone create an option to use. Yes, they will lobby hard and their friends will pass law after law.
