Which is the best for day trading in your opinion in terms of reliability and profit? In terms of profit maybe the cripto, but in terms of reliability Forex. Cripto is like gambling I suppose, you have to check the trollbox, the news and hope to jump into the train fast enough to not be burnt.
People should stop comparing these two things, there are people who are trading forex and they are making lots of money and there are also those that are making good money trading cryptocurrency.
So, you just have to find what you're comfortable with. Volatility is not even reason because forex trading can as well be volatile. There are people who are trying to say that crypto trading is the only that is volatile but that's not the truth, they can both be volatile, except that cryptocurrency has finite supply, while forex is infinite. They are all good, just find what's best for you and work towards being perfect in it.
