The technical analysis are just the same, however, the volatility is not. Trading in cryptocurrency has more risk than trading in forex (depends on how much risk you put in forex though). For me, it's more fun trading in cryptocurrency and easier to familiarize than in the real currency we have in the whole globe. Profits is better also in cryptocurrency, trading platforms in cryptocurrency is much better as well compare to forex.
Also you can avoid lot of hidden fees while trading cryptos but with forex you need to spend a lot for the fee and tax, but when the crypto trading is legal you have to pay more taxes which is almost equivalent to corporate taxes in some countries. But I can agree with the fun part, trading crypto is easier and once we get to know and familiarize with it then it will be more easier than other kind of tradings.
