I think $2-3K BIN sounds about right for an end user. It's a long, exact match... i'm having trouble looking up how many searches it gets... so it's just a guess.
Crypto is hard to buy. People do search for how to do it. This is a build out name pure and simple. There are probably a ton of referral programs to promote.
But maybe they're using terms like "how to buy bitcoin" or "how to buy ethereum" since those are more well known?
