Yea there are bots out there you can program to trade for you on the exchanges, really useful if you know a good bit about trading technics, I personally love the old fashioned manual way but they do work well. Best thing I do is join the coins community or forum and talk with users. Try to always read a coins whitepaper too. What I did in the early days was watch a lot of trading videos, even fiat ones because some tactics in regular cash markets do still apply in this one. For me I am big on Bitcoin, Litecoin, Steem, PiVX (Though I am biased there because I used to work for PIVX lol) I do like Monero, there is one not well known called TransferCoin (TX) that is a lot like PIVX but very cheap...that has some potential. I am not much for ETH though due to the banks in there and definitely against RIPPLE, those two I suspect will be doomed due to letting bankers in there so I avoid them even though they are hot right now, just my purists movement side to me against them.
