I think the coin for you is STQ, aside that before you choose a coin consider coins that have their own blockchain like ether, xlm, neo, Remme.Because this days transaction fees for transferring coins on other blockchains are outrageous
At first ,you have to choose the altcoin as a long-term . Because we can't expect huge raise even in the potential altcoin like ETH, Monero,Waves,Neo. Only in bitcoin,we can expect huge rise.So if you choose altcoin,to inverse your money.You have to hold it for the longer period.
