-snip- I encountered an “additional” commission for sending in the amount of 0.0005 btc, tell me, is this commission for each transfer from the service?
It's noted that there'll an additional (
third-party) fee during the creation of your 2FA wallet, you should've paid attention to that.
Since you have already prepaid for 20 transactions, it would be a waste to disable 2FA now since it's safer to keep on using that wallet
At least until you ran out of 2fa prepaid credits.
You can monitor it by clicking the Trusted Coin icon on the bottom-right hand side of Electrum:
It'll show "
Your wallet has xx prepaid transactions".
You can decide to disable 2FA (
Restore from seed or send to Standard wallet) to before it charge you for the next 20 transactions.
