Well other altcoin, offers much cheaper Gas Fee and Faster Transactions.
In a world where competition exists. Even a big name for its self, like bitcoin. Will always be challenged with another with more advance services and better offers.
Market will be messy but exchanges are keeping there hands full to make it organize.
Depends what the alt coins is built on or if it is its own blockchain.
NANO has 0 tx fees (an exchange might have a withdraw fee).
ALGO, XLM, XRP and VET all have low transaction fees.
Even a token on the BSC has low fees (usually). $BYG is a token I am looking at. It has some series gains lately and actual utility in the Black Eye Galaxy NFT game coming out soon.
