It is good to replace the gambling field by trading, because trading is really less risky than gambling, despite that both are risky of course. In the trading world, you can minimize the risks by getting more knowledge about the market, the studying of charts, choosing the most profitable coins to trade and so on. In gambling, you depend only on luck, and you can't reduce the high risk of losing.
In my opinion, the risk in trading is almost equivalent to gambling, because I have seen a lot of traders getting into debt when the investment products they purchased start to plunge hard in its value. So I believe even if the traders are having a strong knowledge on analyzing trading graphs, they are still taking a big risk whenever they put their own money to conduct trades on the trading market.
