What is G20? That term is just new to me, even though I am almost a year reading articles about crypto, this is the first time I encounter that. Are you telling that the G20 make you calm about the frequent price change of bitcoin? I believe people are the one who managed the bitcoin, it is decentralized thus, no central controlled is necessary just to calm down people from sell or buying bitcoins. I personally managed my own bitcoin and never let anyone managed it to ensure security.
