Maybe the time is not right to choose to buy Solana Coin (SOL) when the price is far below the current price. I think it's not too late to buy Solana Coin right now and it's still the right time to buy it because Solana is one of the coins that will have something in common with Binance Coin in terms of price.
I don't see a similarity between Solana and Binance, because the mainnet is different and the value difference between the two is also there and Solana doesn't have its own big exchange like BNB which owns the Binance exchange, so the two are not the same in any way.
