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.
