Do not give up just because you lost some of your coins. When you did something wrong it means you learn something, so never give up and learn from your experience that is how every traders are dealing everyday.
If you opt into anything without going through the proper channel, then it is always the same way those people will bounce out.
Some people always have the feelings that they can just hit the ground rolling, learn from experience as they go on and once they start losing a lot, they start crying trading sucks. Learn first, practice with little, fail and learn from it and get better before you load up.
