I guess this is mainly for Slávek and Michele, but would you consider adding Nano (nano.org) as a donation option on the TDE site? I'd much prefer to use that over Bitcoin as it's more energy efficient, instant, and has no fees. I've used it for years without issue. I personally use and prefer https://nault.cc as a non-custodial wallet but there are others to choose from. https://blocklattice.io is a good block explorer if you're interested in seeing transactions. Thanks, Mike
