You raise good points. It’s great that other store fronts still exist where you can sell adult games. But I do worry if credit card companies will come for them too one day.

Re: crypto. Some of what you said is true. Transaction fee are comparatively expensive (but also note credit card companies charge transaction fees too, just not directly to the consumer). But other points aren’t necessarily true. Transaction times have improved a lot, there are networks designed for fast transaction times, and usually the payment can complete in seconds. The volatility problem is solved by stable coins, which have their values fixed relative a currency. (Of course stable coins can, and have failed in the past. But that only concerns you if you keep your money as stable coin. For one-off payments this shouldn’t matter). Retailers don’t have to hold cryptos if they don’t want to. Crypto markets have pretty good liquidity nowadays, it’s not hard to get rid of the coins immediately after you get them (well to be fair if you are getting Valve volumes it could be a problem, should be fine for smaller stores).

Crypto is a fast evolving field, so problems are being solved by the day.

Maybe time for some to start a adult only game store that uses crypto to settle payments?
