On the Fireside Fedi interview with Jerry ( the admin of Infosec.Exchange Mastodon instance ) a scary truth was suddenly revealed ( on 34:11 ): Just to keep the instance up and running he needs to spend up to $5000 a month, pretty much out of his pocket. Donations to the instance barely cover any of that. And if he will ask people to pay to use it, they will, rightfully so, switch to a different instance.
Sorry, I mistakenly read your original comment, transaction fees for USDC are actually free (gasless) via Base on Ethereum, eg: https://xcancel.com/coinbasewallet/status/1800653787960406031
Costs mentioned on my previous post are for other assets
Neat, might have to try that sometime
