i would say another important thing, DO NOT OVER-TRADE, i lost so much changing coins while if i had hold for a couple of months i would have got the same gains or more, get a decent coin, set up the targets and wait!
besides over trade, the first rule of trading is
Don't Be Greedymake a little profit with consistency is better than make a huge profit in one day after that you lose your money in the next days
This could be one of the best advises ever and deserves to take its place in the first post.
Never ever wait for additional 1% price change if you already decided to enter into or to quit the trade, set limits and stop losses, otherwise everything can end up with higher loss, or of course higher profit.. but you would never know.
