IMO, adoption of merchants isn't the only way to have a massive increase, we can still achieve this by buying more even we don't spend it. The fact that the value grows significantly, some prefer this to hold than use.

Consequentially, merchants shouldn't be the issue here since merchants isn't open for this, so the least we can do is refrain ourselves from selling, since selling will just make some dips thus buying more is a key to heightened the demand. Actually, this should start from ourselves.
