While I can't speak for those running a full-on sales-and-services business, simple HODL speculation has worked out well for me. I aim to trade rarely and discuss trading even less, so I have simply picked out new issues that have a remotely credible whitepaper, placed a bet, and waited. The ones that pan out become the seed for the next round a few years later. My biggest worry is simply in losing the wallets or fatfingering a trade. The industry as a whole doesn't have to be showing profits or cashflow so long as capital keeps coming in -- and it does, because it's sufficiently disruptive to finance that everyone looks for an angle, and because it's very easy to create new tokens, the money is being made, in some sense, simply by putting out the hat and asking: "is this idea good?"
