All the gains with btc were made already if we are looking for 4 years from now is only 2-3x .
ETH I could see 5X in the next 4 years it has lower marketcap and better roi.
I wouldn't bet on metaverse coin yet because all the project look superb. look at sandbox, decentraland is not look like they have bright future too.
Well it's pretty basic math that there is not much room anymore for BTC to do another x5 or even a x10 from here on as the early investors already made a x1000 or even way more. The same is also true for ETH though maybe not to the same extent but still the early investors of ETH also already made a x1000. What is also a factor that speaks for BTC is the fact that for most people that are not so much into crypto it is still true that cryptocurrencies = bitcoin because that is the only crypto project that they know so if such people enter the crypto space they are mostly investing into Bitcoin first and maybe later they invest into other projects too.
Basic math... we can play with that you know! Bitcoin at $1 million, it's x25 from now! Or you can take Ripple for another example and imagine it's going to be $100 (which is pretty impossible or not?!) and it's over x100... and you can add more examples, but the main question is do you believe that Bitcoin will hit $1 million before ripple hits $100?! So in the end, like always, every investment has its risks and possible gains... it's why we have odds and chances! Please don't get me wrong, I am not arguing you here, I belive there are some coins that can make x1000 or more in the future, but they are riskier than investing in Bitcoin and waiting for some safe return!
