I felt the same way for a while about investing btc in something and not getting as much as btc. but i chose to leave btc, i made the choice i have to live with it and so should you. maybe its a lesson in only buying the top coins and ride the slow wave or you invest in a start up that is risky.
and besides i put 400 in mgo now its 530 after six months that is 32.5% I think most of us got in at the same amount. unless im wrong. i have no complaints. this is a foreign market coin. it will be big in china india and japan other countries with programmers who want to make their own games and monetize them. Implementing that idea will takes a few years not months. you can always sell.
I won't sell, I ride MGO based on the ICO price and I feel I lose money with today's price, until now it's not yet growing although the price of bitcoin has really skyrocket, but I believe on what you said that it will take years and I am willing to wait for that time.
