There is nothing bad to go for forex, but I do not understand you correctly, did you know that there is something more than only investing in crypto? There is crypto trading too. But if you think you can not go for crypto future trading, you can go for forex, but you can also open long or short position on exchanges like Binance, OKX and many others using crypto.
because currencies rise and fall all the time and their fluctuations can make you money if you can position yourself correctly.
Trading is generally risky, be it crypto, forex or stock.
I'm only wondering what kind of information you base your trading positions on ?
Technical analysis is very important in forex but fundamental is also very important, you will have to know the latest news in the countries you are using their fiat for trading pairs, you will need to read more about this and how this news like change in interest rate, inflation can affect fiat value of a country.
In crypto, sometimes we research a project for a few days before deciding whether to invest on it or not.
You are talking about trading, why talking about investing too? Do not misunderstand crypto investing to crypto trading.
