Yes, there are good options like Real Estate, Gold, and Stock market even these are also risky but the risk factor is very less as compared to altcoins so most investors or traders invest their money in these, on the other hand, there are investors who do not afraid to take the risk so they invest in altcoins. I start crypto in late 2017 and I never look back even 2019 was the worst year for most of the crypto trader who believes in holding. I am happy I earned good money from this market because of my patience level of holding so I would say investing gives a good return only when you have patience also. I support this because I know this market has huge potential and those who are associated with crypto will get the most benefit.
