Yeah would be concerned with anybody putting any money they really can't afford to lose into any crypto coin/asset/platofrom including BTC. It's all high risk/reward. I totally get the excitement, pretty sure all of us here do except the trolls and people hired to spread FUD and cause divisions and fighting of course. Sometimes when someone has decided there is no reasoning with them, so here is to his success I hope. I certainly am not all in, I have a diversified crypto spread I think. But If you're luck lands on the side of reward and not risk when you want to cash out, then the all in people will gain the most. If not, they may lose everything. I would just say my personal experience is one of seeing lots of unforseen events taking place in this space. Sometimes good, sometimes bad. Recently I invested in ETH and the DAO, lots of hype around the DAO. They were the darling of the alt news. The code was supposed to be safe, was audited by a respectable crypto auditing company. And then as soon as it came it went. Hard fork saved DAO investors funds for now, but tha's another story. You never know what is going to happen around here. Anybody that tells you they do, is most likely ignorant. Good luck to us all!!
