for several reasons, maybe:

capital is cutely minimal

readily accessible

universally accepted

little or zero knowledge about #BTC

no need for any hardware to mine

get-rich-quick state of mind

one-time big-time

nouveau-riche looks normie

#BTC is not as readily-accessible as $$$

no government support for wide-scale propagation of #BTC

#BTC is digital gold, not cold $$$
