Sorry to hear :/ Did you do the proper research in the projects before investing?
I really think some form of regulation in regards to ico's to shut down all of the scammy projects would be extremely beneficial. But when it comes to project simply failing it's part of the game and why we need to be very careful when choosing where to invest.
Genuine failures happen everywhere and not just in the crypto-world. But I am more concerned about the scams in which the promoters take all the ETH from the participants and then vanish in the think air. Anyway, it is good that a lot of the countries are starting to regulate the ICOs.
