Once it starts a convincing recovery then vendors will flock back to it. There has been many problems for vendors on the darkweb for example, due to the combination of escrow service with a market correction means vendor losses can be upto 50% over sales due to shipping times.
The point here is darkweb vendors have to use crypto despite the market correction, they don't have realistic/secure fiat options, but any legal vendor wouldn't be bothering with similar risks until the prices are stable, or at least going back into green.
I find it ridiculous really, the drug dealers never complain about the volatility when it's in their favour

They should just learn to HODL/trade a bit more.
