investing is an art, Some kind of instinct like the 6th scene, Not only in altcoin but in anything else, You have seen or heard about reach people in real estate marketing or any other market, the rules are the same, buy low sell high, but to find out the enter and the exit point make the difference between a natural trader and a newbie, I wish I could tell you how to gain that instinct but I can't as it is some inner voice, you can be a professional trader and make some profit but to be a big wealthy person like Trump you need that instinct that only a few have it.
