Bitcoin is a wallet that I really appreciate for its fluidity in transfers. But one thing that I don't like in the operating mode is the long duration of the transfers or even 30 min to two weeks. Why not make the transfer as simple as possible since if we make a transfer, it is for very specific purposes which are not for a long period! Also the management of this project must look a little at the costs of the different transactions, the costs are a little too high for me. We will work well with cryptocurrency but not that way!
