Hello,
Today is Open Discussion Day:
http://www.opendiscussionday.org/It means that, for one day, one should try to not use any closed/proprietary protocol. This includes centralized protocols.
I thought that the concept of protocols might be extended to money. So, today, try to only pay with decentralized money :
