Yes, I agree with you. In the trading, crypto or forex trading, we really need to have experience and skills to get the right coins so we can make a profit. And that will not be the same as gambling. When you don't have luck, then you cannot get a win. But both, gambling and trading will not be easy to make money because we need to know the right timing to enter the market. In gambling, we need to know when we can stop gamble, so we don't lose all of the money.
Entering the market is absolutely not a problem, especially if you enter such coins as bitcoin, Ethereum, they can restore their price even after strong falls. The whole question is just about waiting time.
In order not to lose a lot of money in gambling, you need to be able to determine for yourself the amount after the loss of which you stop playing.
