In 2018 governaments will regulate cripto and some of them will forbid them. Is that true or false?
Governments can't control cryptocurrency. They can't ban it either. Just take a closer look at for how long they are trying to get rid of pirating over the internet? It simply can't be done because this is peer to peer tech, same applies for bitcoin and other cryptocurrencies. Thry could however try to find your IP but then you could easily escape with some private VPN... banning is not an options.
It can't be regulated, they might try to regulate businesses around it like exchanges, merchants etc. but they can't regulate individuals. You can always mix your coins with bitcoin or even take some anon coin such as monero which is popular solution out there. It's really hard if not impossible to regulate it and tax it. It was made that there are no regulation.
