If you have 1000usd in your account, my recommendation would be BTC2 and QNT, because they have a low supply compared to the others, and i know that this project will be able to grow in the longer period of time, BTC2 is a hardfork of Bitcoin so that is why, im gonna recommend this one. Anyway, there are also best coins nowadays, but i only stick to the project where the teams are consistent to their roadmaps.
