Let me explain What is BRC-20 and why for the token is FREE.
BRC-20 is chain that working in BITCOIN network and yes that is same like ERC-20 of ETHEREUM.
The different is the token called as fungible token and you need to pay gas only to get the token. No matter how much you can pay for the gas, the priority is the highest payers will get the token first. You will lost your money if there is no more token and your transaction will be failed then your money gone…
Inscription is the only way for you to zip your token so you can send it or sell it. Every token that is not in Inscription cannot be sell/transfer.
