What I am still concerned about is how the fee (I mean the transaction fee) of bitcoin could be while making transactions (I mean the onchain fee), when BSC is already existing which people can make use of with very low fee, including ethereum which its fee is though high but bitcoin fee will be slightly higher. Both ERC20 and BSC20 are existing already and there will really be need to have a bitcoin smart contract that can be used to make use of low fee effectively. Although, people like bitcoin because it has the highest marketcap which will make it for large number of people to make use of its tokens.
Many people today are concerned about Bitcoin free. BSc already exists because there is less free in current BSc. Ethereum may have been less free in the past but now Ethereum takes more free so everyone uses BSc and what is paid for BSc in most bounties. It is true that both ERC20 and BSC already exist. Bitcoin needs to be a smart deal, if it is, it will be less free. Bitcoin is currently used in most countries.
