I ve been watching the video, see below, but it is in French:

It's a banker more than 30 years in the business (he is working only with small and medium companies) talking/giving his opinion about BTC. He is in favour in BTC although he does not own BTC.

So,He was comparing the status of the Gold and BTC.

He was saying every morning in London, a few companies meet to limit the price of the gold and so the volatility. And for him, he was saying that for BTC to work as "Gold Standard", BTC will have to find a way to limit the volatility (otherwise BTC never be as "standard gold"). And one of the idea was to create a vote between all the participants in order may be to write a smart contract to limit the volatility.

I suppose this topic came many times on the table, will the solution could work (creating smart contract to limit volatility) ? or are there any thought about it or solution that can prevent the volatility?.
