Thank you Ucy for your reply

I checked your latests posts but I was unable to find the ones regarding bitcoin volatility, could you please point me to the posts you are referring to?

Just to clarify: the protocol I'm trying to implement converges towards a bitcoin-only currency system. The temporal usage of a stablecoin is to allow, simultaneously, for people to transition from fiat to bitcoin, and to make that transition smooth for the average citizen (while investors will withstand the brunt of the volatility).
