Everything is changing very quickly and in times like our time, so demanding and where everything is analyzed in detail only the structured and valid projects will prevail, no one want to be in weak projects and I don't know if Libra will be a successful project, if it will is liquid it will also not be full descentralized but I guess nobody knows if will be good or not, there are to much and new things to happen in a short future.
On regulation, it is obvious that one day the most valid projects will be the target of greed by the governments of global economy. It is up to decentralization thing to stand and remain autonomous and free.
