If one did, would it be a good idea to be constantly advertising that fact? What if authorities crack down? It's supposed to be stimulus and not take the money and stash it in your own monetary system-ulus.
i'm sure the government
hopes people spend the money on consumer goods and services. that's the whole point of direct stimulus---to stimulate the consumer economy, not to stimulate the hoarding of investment assets or cash.
still, there are no restrictions on what people can spend their stimulus checks on, so why would it matter? there's nothing illegal happening here.
in my case, $600 isn't worth that much thought---that's ~0.02 BTC. shrug. i have no specific plans for it.
