If crypto could be introduce in traditional market it will be awesome, unfortunately it's not that simple, the legality of crypto still in big question mark, and then the popularity in crypto is not too good in some countries, so I would say it need more time to introduce crypto to traditional market
Some of the countries (India) still think that crypto investments are like pyramid schemes, many people may lose money and the only handful of people will make money from these investments. The second issue is people can use cryptos for illegal activities and government agencies not able to trace them so legalising or regulating cryptos may take many many years. But whoever early investors may have good chance to make a good profit in the future so I think it is better to invest a small portion of savings in cryptos and wait.
