50 minutes and an "undo" option? That doesn’t seem like something the community would support.
Bitcoin’s whole purpose is to scale and provide fast, irreversible transactions. A 50-minute wait time and the ability to cancel transactions go completely against that purpose. It would make things messy, like following the model of some fiat digital wallets.
In our country, one of the wallet providers actually introduced something similar, and while it may work for fiat, it feels out of place for Bitcoin.
GCash cannot automatically reverse a completed transaction, but you can dispute it
Some users like it, but we are not fiat, we are bitcoin,, so we don't follow their style.
Strange conception you have. Bitcoin general advise is to wait 6 confirmations, this is not unnecessary, it's the way bitcoin works internally, it's possible for their to be multi-chain/multi-end points, basically a race condition, where multiple chains are the longest, only after some time will one grow faster than the other.
