Agree! The most worrisome is housing, I still have memories of 2008. The ripple effect of any housing market downturn will once again be extraordinary. People are paying 3-4x more per square foot than what we bought for in the same neighborhood 15 years ago. The buyers today aren't getting a good deal as the mania has swept so many up.
I think bitcoin is just a "Robinhood" thing as not many have more than a trifling sum invested there. Having 5% of your investments in it won't make much difference in the long and those who brag to be millionaires on twitter have no concept of what risk really is. Luckily most of us saved appropriately over the years and don't have to try to shoot the moon on a wild speculation of digits on a hard drive.
The likely response is Fed hedges their answer as to when QE Infinity ends. They could say, "we're going to ease until the pandemic is over." That can be tomorrow or... really infinity.

Either way, the bugs kept saying the dollar collapse would help gold. It hasn't, so maybe inflation isn't as big a problem as some think.
