i got some Bitcoin back in 2012-2013 when people would operate faucets. i realized most of those faucets worked by displaying ads and just giving users a cut of the ad revenue. i spun up my own faucet on the same principle and made a bit of $BTC that way. since the ads only pay for human impressions, i gated the faucet behind a captcha, but i got clever and wired that to an API where the captchas i showed my visitors were actually sourced from 3rd parties who wanted their own submitted captchas to be solved by a human and were willing to pay $ for that.

i killed the whole thing a month later once i properly confronted the fact that i was enabling bulk spammers by doing this.

since then, i’ve used crypto to purchase VPNs, shared data replication (i.e. i want to backup 1 TB of data offsite, and also i have 2 TB of free HDD capacity: i’ll back up your data if you & a someone else backup my data), and the occasional donation to charity or “content creators”. i used Sia/Siacoin for the storage bit, but the UX was a little weak and i’ve just gone back to Backblaze in the meantime — will revisit the area at some future point. as for the donations bit: it’s nice to be able to donate to a project anonymously so that it doesn’t impact my relationship with the devs/artist/etc. even “independent” media outlets are in a weird place where the desire to keep advertisers causes a bit of self-censorship, but the authors don’t want to paywall their work because that limits their audience; sponsorship (Patreon style) plays a role here, and enough people have been bitten by Paypal/Patreon/others that things like Bitcoin have a small foothold.

i’ve also used cryptocurrencies to purchase medications before getting an official diagnosis, and then take these findings to my GP or a specialist and get proper prescriptions for whatever treatment worked best. it’s generally faster and a bit more intuitive than working through the official healthcare system from start to finish, and people have so far been surprisingly receptive when i list my symptoms and then say “by the way i’ve tried medications X/Y/Z and had the following experiences with them: …”. make of that what you will.
