Yes, it's more or less like that and basically any trade has its own risks,so again it depends on each person which one prefers in trading and they certainly have their own choice, Talking about crypto trading is indeed very complex and the crypto market itself is also very volatile so preparation is needed before starting to trade or invest
Same things are applicable to crypto and forex, both. It takes time and experience to gain the knowledge and skills to trade on a specific market and neither one is better or bad than the other because it is a personal choice. Both are profitable and both are complex but neither is better than the other in my opinion.
As much as you prepare, some risk is always there with any speculative trading, so matter the type of trading, losses will happen.
Crypto is what the users of this forum are familiar with. Some have come from a forex background while some have not. So it is not the best place to get an answer to the OP's query.
