Thanks for sharing this post. According to what I was reading there are several currencies whose objective is to facilitate transactions. Minimize times and costs. One of the ones I have in mind is IOTA, supposedly for current use as green paper. Apparently it has a large volume and a stable price.
I hope that in the near future we have enough confidence and everything is prepared for the current use of cryptocurrencies. I have a hairdresser and we accept many cryptocurrencies.
