I tried reading and understanding the process, but it is still confusing.
I get the Error Message: Transaction gas is too low. There is not enough gas to cover minimal cost of the transaction (minimal: 21000, got:1). Try increasing supplied gas.
I type 21000, but I still get an error message.
How do I get to understanding GAS
Do cold wallets have to use GAS? ie) Trezor/Nano?
On your case maybe you dont have enough ballance on your wallet to make any transaction.
Try making your balance at least 0.05 eth this is plenty enough to make any transaction you want
