I am familiar with economics before going into bitcoin. I am totally fine with fiat system and the money printer even, and I disagree with most that the inflation is largely caused by money printing (just take a look at Japan decade long QE policy).

But essentially the US is running a modern monetary theory system, and that is extremely concerning. If you are concerned about mRNA vaccine, then this is way worse. This is gambling on the fact that Japan didn't have any issue, and that they printed a large one before.

I understand why they want and need to print, but at the end we don't know how many more times they can print. It could be this or the next QE, or the next next QE and everything blew up.

I think it would take a few generations and complete collapse in fiat system for normal people to take bitcoin as default currency (especially since bitcoin will always be volatile due to hard supply curve), but I can see that happening.
