If you are interested in trading, I highly recommend @quickfingersluc on steemit
https://steemit.com/@quickfingerslucHe is an experienced day trader that explains some easy strategies, and informs you on the tools you need, and practices to be safe with your money.
For long trades just don't buy on a pump. If you are really scared of missing out, check out lucs most recent video, near the end he talks about a good entry point into a coin going parabolic. Once the market has corrected a little then that is a good time to buy. Or if there is a coin you really want to get into, and it drops a lot for no apparent reason, that is a good time to buy! It seems counter intuitive, but when people panic sell, if it is a solid asset, this is the time to buy (because it will pop back up and you got it cheap).
