I advise you to pray and hope that the project of the coin you invested will continue to run and have progress, so that the coin that you invest can have value and many investors will believe to investing in these coin, then the price of the coin you invest can increase very high and give you a big profit.
No more day dream, that is a complete loss for the OP and it could be added to wonder of the world is such things happens in reality as you said.
Don't buy coins based on its price and price growth, it is always important to check the development stage of the project and the team behind it.
