When you say trading as gambling it will only apply to futures trading which makes one will only do the guessing whether the price goes up and down
or Long and Short, It does look more like gambling.
But when looking at Spot Trading, it's not like gambling at all.
You will only hold the assets you own and can sell at any price, even if you guess or your prediction is wrong the asset you will still have.
You can be sure the two concepts of futures and spot trading are very different, especially when talking about the category of Binary options trading that only takes advantage of crypto market price fluctuations without holding any assets and only risks your Fiat for a chance to guess long or short (this is more risky).
And in conclusion you can't say gambling equals trading because it has several types of trading, you have to be more specific.
Also, trading on futures needs discipline and you should react quickly and should have risk management because if you don't have knowledge about risk management, TA, and FA then that's a gamble like no stop-loss, you buy or sell when it is on overbought or oversold if you keep doing that instead of making a profit you will lose all your capital.
The other advantage of futures is that you can also trade on a short position when bearish unlike in spot trading you will lose if you keep holding or you will end up selling your coins just to avoid further losses.
