re: Why are so many ppl still hung up on the “non-physicality” or “non-productivity” of BTC?

Bitcoin has no utility, which makes it extremely hard to value. It is a pure greater fool theory in action. However it doesn't mean it will crash overnight. All of the utility use cases have basically gone away over the years as everyone knows Bitcoin basically only value is being digital "gold".

Obviously gold has some utility especially in electronics, jewelry etc, so not sure it's a fair comparison.

I think the biggest issue is the bad actors in the space such as tether which obviously have strong ties to bitcoins price.
