Cryptocurrencies (or just alternate currencies generally) are actually a pretty neat idea for getting around resource limitations.
Imagine if the DSA created a new currency: DSA Bucks (DBs). These can be used to pay your group dues, get into group events with cover charges, or buy DSA merchandise at a rate of $1 per DB. You can get them by buying them at that price from the DSA, or by doing stuff for the DSA or selling stuff to the DSA in exchange for payment in DBs. There could then be the standard cryptocurrency online marketplaces allowing people to sell their DBs for dollars, presumably at a steep discount since obviously a $1 DSA coupon is not worth anywhere near a $1. Still, there would be some demand since everyone in DSA is paying dues, and there’s a lot of money to be saved by buying DBs at a discount and paying dues in those rather than donating the dollars directly. If there’s a decent sized marketplace, which there presumably could be if this was rolled out at DSA chapters nationwide, the currency starts to gain real value and the DSA essentially becomes a currency issuer.
