If rent payment takes too long, rental should be cancelled and funds (with BTC tx fee deducted from them) returned to payer after his payment is confirmed - because it's renter's fault to make a mess with wrong tx ammount or fee - right?
I think a straight forward solution to this problem is to introduce an online wallet on betarigs -> Rigs can only be rented, if there are enough funds in the renters account.
This would solve 2 problems:
1. The renter doesn't have to pay a transaction fee on each rent
2. The rig owner does not have so long "downtimes" since the payment would be instant
Mux, I hope you consider this, it would add a lot of value to betarigs!
Kind Regards
