This is a serious discussion. I mean, after I've seen how bitcoin (and other cryptos as well) got dumped badly after an irrelevant law that makes ICOs illegal. I can only imagine now what would happen If more countries do the same thing and It could get worst by make itself bitcoin illegal. Whether we like to admit it or not, most of people would sell everything they have once its made illegal, some may continue to fight the central banking but the sad reality is that as soon as people start making profits, they will dump it and move on.
But that only makes icos illegal, that does not ban crypto in itself, that just means that the developers cannot expect to get millions of dollars without having anything ready, if they want to obtain money they are going to need to do it by supporting their coins creating giveaways and creating support for their projects, I like it, this way we are going to see better coins and not just attempts by scammers to make a quick dollar.
