Crypto trading is more accessible and democratic than forex trading. Crypto can be easily accessible to everyone around the clock, even those without access to traditional banking. Only an internet connection and a crypto wallet are required. Forex trading, on the other hand, requires a broker account and may have higher fees and commissions.
Crypto trading is more transparent and decentralized than forex trading. Forex transactions are mostly done through intermediaries that may not disclose all the information or act in the best interest of the traders.
Crypto trading is more innovative and diverse than forex trading.
But then again, we're not even talking about crypto trading, were talking about it's investment. Trading in both forex and crypto is risky, but crypto shows more advantages than FX. Investing in cryptocurrency is the best. There's less risk and your interest rate is way more than anything financial institutions can offer.
And also you spoke about knowledge gained. Investing in cryptocurrencies also teaches one about better investment options, trading skills, economic trends and so on . So OP, it's investment for me.
