NEVER ever go for that. You may become disappointed at any time.
The best practice must be risking only 5% to 10% of your portfolio in altcoins is always recommended.

What we are having right now due to dogecoin/etehreum is not a sustaining one. Moreover these may happen once in 5 or 10 years, you cannot dream about that on cyclic manner how people are enjoying assured profits with bitcoins on every four years. By the way, I never heard about SOL so far, what is that?

ETH might be trading around its ATH of life time right now, investing with that may become a life's biggest mistake as well. Same the case for Ada. ETC may become dead at any time.
