Advertisements are one thing but most of these "ads" are actually gathering more info than they advertise. JavaScript trackers are just awful if you care about privacy, which I do. It's pi-hole and no-script all the way for me until they stop with this rubbish.
Targeted ads are another kind of problem. I don't really want to be told or suggested what I should or could buy, I can make up my own mind. I know some people don't mind them and that's fine.
Well technically it does. Just not if you buy from coinbase where they need a lot of your personal information plus you'll be most likely buying with a debit/credit card.
If you pay someone for cryptocurrency in cash and they send to a wallet you have set up by yourself there is not really any way to prove that it's yours.

In all honesty I preferred the annoying pop ups.
