I think this two are the same thing if you are calling about Investing in coins and later on trading them for gains then it is the same thing. However if you are talking about crypto investing in terms of earning daily/monthly fixed income then there is no legit option out there and all of it are just scams, the crypto industry is so volatile that giving a fixed rate on a daily basis is really not a viable way for any businesses out there. The closest thing you can get as an investment in this industry is by purchasing STOs as these are closely related to stocks in terms of them being directly linked to the company's financials as well as it paying dividends for its coin holders.
