I accidentally sent my MEW private key instead of wallet address to this Google Docs Airdrop. Is it possible to replace that private key? Thanks a lot!
As far as I know it is not possible to replace the private key. The only way, if you do not want to lose all the coin that you have, you need create a new wallet and sent all to it.
agree.if you can not change it. Because it is a security key, if it can be changed, security will no longer exist. If you lose your private key, immediately transfer the coin to that account to another wallet and create your own account. So my advice you should be careful about protecting your key.
