I think we should be very careful and meticulous in investing in criptocurrency, it would be nice to ask in advance to know that ICO is really trustworthy
Always invest money which you can afford to live without so that even if the price drops you can hold for longer time or you get scammed just in case you are still ok rather than investing your entire saving in crypto currency. One has to be careful as much as possible and avoid anything which you do not understand.
