Do the wallet allows to redo transaction with fee?
I am actually put a fee for the transaction but i dont know when i send the connection is quite slow. Maybe my internet connection is bad. And suddenly i saw the fee is zero.
And 1 question. Will be bitcoin loss??
After you convert, Blockchain says https://blog.blockchain.com/2016/03/16/introducing-dynamic-fees/ so it will calculate an appropriate fee depending on the current traffic. The speed/quality of your internet connection is not the problem.
No. Even without redoing the transaction to add a fee, odds are eventually the transaction will be included in a block so, no, the bitcoins will not be loss.
