yes it is 2FA transaction, i tought 2FA is just a security measure thats why i created that kind of wallet. It seems that you are right...but 50 bucs fee is just insanse. I use many apps with 2fa and there is never an additional fee, to me this is just a blackmailing from electrum. Very disapointing.
Electrum displayed a message about the additional fee when you were creating your 2FA wallet, but you probably ignored it and clicked on "Next" without reading the message.
Electrum 2FA wallet is a 2 of 3 mutli-signature wallet and when you make transaction, the 2FA provider (trustedcoin) must sign your transaction as the co-signer. You can't really expect them to provide the service freely.

In my personal opinion, they just play bad, they hope at least some people will use the service without to pay attention and they gonna do a huge profit. I do not see how the adoption will go with these cheap tricks...on the other hand ledger are ridiculusly overprotective and so unflexible because of that. So much scam and cheap tricks in this crypto world./
