Cryptocurrencies can be even for people who are not that familiar with the market and how it moves, they just predict that the price will go up in the long run and that's it. But with forex? That is hardly possible.
Believe me, a lot of people unfamiliar with forex jumped in anyway. I recall even in the early 2000s when e-gold and Paypal, and then later even Liberty Reserve were easy to access, people were flooding to forex sites with accounts giving $5 no deposit bonuses. Suddenly it was easy to see your money double on margin trading, people were just doing long or short randomly. The experts and the signal sellers were plenty, 10 pips a day for double your money in a month.
Much of the same is happening with crypto, I feel. Even without margin trading, you have those satoshi pumps. Just scout around the forum especially in Speculation threads. Pump groups. Signals. Bots. So much of the old forex pattern emerging.
