You are not the only one who has gone through this issue. I remember investing in some few ICOs that did not live up to expectation. Some, it has taken some months now and the coins are not even listed on any exchange. Others too, just disappear into thin air with their social media pages deleted. Its quite painful to go through this experience.
It must be understood from the outset that any investment is a risk. But if you don't, you will never know how much you can earn!
