How did you come out with that belief it's like saying that if you're poor, Bitcoin is not for you, so you should settle for cheap coins like Solana.
Just to enlighten you, you can buy $10 Bitcoin, and you can still make a profit, we have proven Bitcoin profitability for over a decade.
Solana is good, but I don't think it is better than Bitcoin in terms of profitability, market cap, and popularity; Bitcoin is a highly stable investment. You just have to be patient to reap the profit.
if there's anything that could be used to determine whether a coin is for rich or poor it'd be the fee imposed on the blockchain like ETH back then where it requires $200 just to mint NFT or to swap coin.
since cryptocurrencies can be bought in decimal amount, using the price to determine whether it's good investment for the rich or the poor isn't really the right thing.
even BTC which OP called out as a coin for the rich only require cheap fee, so it isn't exactly coin for the rich but coin for the people who seek opportunity.
I would assume that bitcoin and sol both do not have a possibility to make 100x from now on, so if you are poor and want to get super rich super quickly then you are not going to find that with neither of them, and there is no reason to invest into anything that would not make any sense for you to invest in the traditional market neither since that's not designed in a way to make you richer, it's designed in a way where billionaires keep getting enough, and that enough isn't enough for you unless you do it for 40 years, which usually loses most of it to inflation but could be decent after a while, maybe retire decently.
So all in all, I believe that we are going to end up with not a good result if we are not careful, which is why we invest into bitcoin, which gives us less than that 100x crazy wildcard tokens, but gives more than some blue chip boring stock as well. Both Bitcoin and Solana are good for that and there isn't really anything benefiting anyone.
