To be honest my goal may be different to yours, my aim is to collect BTC. I spent months sitting on coins I believed in which gave a slow and steady growth. Now I have no attachment to coins I just go where I see a quick 5-10% once I've got enough I will put some into some longer term. I don't like to give advice on coins but I think Ada looks good long term, I think ripple will eventually peg around a dollar as it's a bank coin. I made a lot of profit from TRX but I'm not sure about long term.

My advice would be don't get caught in the hype ( from personal hard lessons learned ) stay away from the small exchanges as they are manipulated by bots.

Do your research on coinmarketcap.com

Hope this helps
