Selling shovels to fools. Silicon Valley's favorite biz model since the roaring 1840s. You do all the mucking around in the mud, we skim the lions share of the profit from the few lucky enough to make one, and leave them holding all the worthless capitol hardware in 6 months time.
My play is to sell deluxe bespoke organic earplugs to quiet the wails of the Cryptobros. 16 tulip bulbs to get in on the ground floor.
