I am very skeptical that in this portfolio there is a chance for a x22!
I have many doubts also in medium term (10 years) if there is only one of these coins capable of making a rise like this...

I have a similar opinion to you on this. Maybe, if he can afford to hold these coins for two bull cycles, this list could lead him to his goal. Also, if I were him, I would change my list to a short list of more solid coins like BTC, ETH and ADA. XRP, SOL and XLM look like fading stars. I think it is possible to make a lot of money with a solid portfolio without taking any risks, but it takes real patience. I hope everyone stays in solid cryptocurrencies and shows the necessary patience. I wish everyone good luck...
