I used to love Sync, but hear me out: Infinity is FOSS and it currently is much nicer and easier to use.
I'm grateful to the creator of Sync for bringing over the app to the Fediverse, and I'll never begrudge anyone for sticking with it or even paying an outrageous price to not have to see ads even though Lemmy has none to begin with. All I'm saying is, you just switched from Reddit to Lemmy, now's the perfect time to try something new.
I've dabbled in crypto and I use Revolut extensively when traveling. When I saw Revolut was starting to push crypto, I got really nervous about their legitimacy as a financial institution.
I'm glad they're getting out.
