Oh, that's interesting. I've only ever used 3rd party for Neo and Stellar.
Maybe Iota and Tron also have 3rd party out now. I actually rarely plug it in these days as I use it more for savings. I have a software wallet I use for buying stuff when I need to. I don't really want anyone knowing my savings addresses, so if I need those, I'll wash them through Binance.
The slow and steady approach for Cardano is really great. I focused on Steem way too much during 2019 and really didn't look into anything I haven't already invested in. I do plan to get back to the others I neglected last year, but are on my radar.
