Solana is included in my Portfolio, but I think solana is not the fastest, because you have to print the address of the token in the address of another wallet if you want to see the token in your wallet list, it requires a fee and a little process, what if one day the price of SOL reaches $500, is it possible costs to be low? for fast transaction fees and low fees, in my opinion, Matic and BSC are still cheap.
