I might write more in-depth predictions on tildes, but for now the most egregious I can think of is on the change around the cryptocurrency space.
It'll probably still be around in some form. If cryptocurrencies themselves are still around by 2030 (seems likely) it'll look very different to today. Probably much more regulated and less fragmented (or on its way to standardize on fewer currencies; also fewer single-use-case currencies). If cryptocurrencies are successful 10 years from now, there will be a few government-backed ones at least. Libra (the Facebook one) won't happen, but something like it will be tried again, probably by Google or Amazon.
ICOs will be considered a joke and the scam of last decade. We'll look back at people falling for crypto scams in the 2010s like new web users fell for Nigerian scams in the 2000s.
Edit: just to try my hand at an extra prediction here, I think the rise of streaming services around tv means piracy will make a strong comeback with Plex and the like; and gaming will increasingly be streamed as well (think Stadia, but something that is successful, maybe by Steam). This may be more of a 20 year prediction but I think game developers will actually adapt their code, engines etc to better support the entire gameplay being streamed (latency-sensitive games becoming less mainstream).
