That's the thing, I don't think it's fair to characterize it that way. Aside from QE, there's no real sign that "massive streams of money" were "dumped in" at all, outside of the three QE rounds. Here's a graph from the FED where the three rounds of QE are highly visible spikes: https://fred.stlouisfed.org/series/BASE
A weird, philosophical skepticism towards fiat currency and an irrational belief in high rates of inflation even without any evidence for it has been a common folk belief amongst goldbugs for decades. (Side note: what's the cryptocurrency equivalent of a goldbug? A bitbug?)
The general mechanism for the FED to influence the money supply is by borrowing and lending money with commercial banks. QE is only really used as a last resort.
