hello ! I am trying to swap some of my usdt tether to bitcoin but it says that i need at least 0.0014 amount of eth. now the problem is i do not have any eth i was gonna buy some but it says i need a minimum amount of 15 usdt to swap usdt to eth.
When you make an on chain transaction, swap in this case, you must have a native currency of that chain. In this case, the native currency for that chain is ETH because you are using Ethereum blockchain.
You only can use your money to buy ETH, and deposit that ETH to the address, and use it for swap. If is similar when you want to swap any ERC20 tokens on Ethereum blockchain, ETH is always needed for transaction fee.
is there any other way for me to get the amount of eth (0.0014) that i only need without having to buy the minimum amount for swap?
No other way, if you don't get donation from anyone else.
