you can get some profit if you use long term method in crypto trading.
It's not trading if you hodl for a long term it's investing, anyways, when it come to investment both stock and crypto have possible to get a high profit if the product that you buy or invest have potential to grow, so if you invested in product that it will not grow, will you lose some of your money. So much better to learn and take time to research before you put your money in investment.
Forex and cryptocurrency trading have very different technical because in forex, trading with both up or down but in cryptocurrency we only get profit if price going up and buy when price down.
For me, trading forex or crypto have each pros and cons. Risk involve also very different. For me i prefer cryptocurrency trading.
