I dont want to make large profit in a short amount of time... i actually want to hold the coins i mined, till they rise and want to know if it is worth and even possible to do that.

things like this can't be in 100% correct prediction. many groups in telegram or other social media who have analysis to hold the coin which one to keep and which coin will increase the price.
for example the case of ETH coin price, no one can predict 100% correct that ETH coin price will be like now. April 2017 price 1 ETH $45.
conclusion, only you alone can decide.
