I hear a lot of people discussing the M2 money supply increasing and that is good for risk assets like bitcoin. This has happened in the past but we need to be aware that if M2 increases rapidly it can cause inflation and the Fed will reduce liquidity and tighten monetary. That could have a negative impact on bitcoin, so don't rely too much on M2 and consider it a reliable indicator to predict bitcoin's trend.
As for whether bitcoin will overtake gold? That is unlikely because a speculative asset cannot overtake a safe haven.
Many people think that Bitcoin will move just as Gold is moving or you can say it is lagging behind the Gold price. Other people are monitoring the liquidity and M2 money supply but again it is not guaranteed that Bitcoin will follow this too. Many people are taking high leverage trades only because of these factors when there is no correlation between them. And for the Bitcoin to surpass gold, it can happen someday but is is not going to happen within the next 5 to 8 years.
