I think you should look at the volatility of gold after Nixon took the US off the gold standard. It looked a lot like BTC. Also, you mentioned gold over centuries...not one of those centuries was spent in the digital world. Most is leaving the physical and entering this realm. There was a time when aluminum was more valuable than gold.

I agree about the currency but not for the reason you mentioned. As big money enters and the market size of BTC grows, the volatility will die down. However, there is still the issue of slow transaction time and the cost. It really isnt feasible for a $2 cup of coffee.

Ultimately, the Wall Street trillions are going to roll into the crypto world and bitcoin, because of its liquidity, will get a lot of it. Bitcoin will only continue to grow and attract developers because that is where the money is going.
