I have been running a live trading youtube channel for a couple months now
You can scope it out here:
http://www.youtube.com/user/lowlight1974/liveI have been killing it in crypto. I started with $1500 and bought in when BTC was at 3K. I now have a wallet that values at 21K and I've not put a single penny into it since my initial investment. I've just been rolling dice at a BTC faucet called freebitco and trading. I coded a bot that does the rolling for me on freebitco now and I also coded a bot that does micro trading on GDAX.
As for coins that will be hot in 2018, Vertcoin is the next Litecoin. EOS is the next Ethereum. And Bitcoin is the next Bitcoin
My own holdings are ETH, LTC, BTC, VTC, DASH, and soon to be EOS.
