No it isn't, Ive been a forex and stocks traders in the past. I can able to tell the different among forex and crypto trading. We are trading centralized and a decentralized stuff which volatility is expected to be entirely different. Since you do ask about the spread then its not really like the same yet PIPs on crypto spread is on thousands of unit which isn't comparable to forex only 0-10 spreads depending on the broker. Profitability? I would say crypto would give the chance but it is more really risky than forex in my own view.
