In my case, as I use it exclusively as a store of value, I am satisfied, but I hope that later on it will be more accepted in commercial establishments such as grocery stores and markets.

Vendors that accept it. They would need to sell stuff I want to buy anyway. Maybe waiting for block would be an annoyance for eg. at grocery store even though it is only around 2 min avg. Guess it should be possible for the receiver to read the amount when the transaction is detected, before it is in a block?

The resource consumption.
