Instead of day manual trading looking at a screen all day how can I earn interest on bitcoin? Preferably automated. Like a passive income you know what I mean.
Why do peeps buy bitcoins off localbitcoins.com when they can buy it cheaper at exchanges scam free?
I think poloniex had such a thing, where you could lend money to margin traders for a daily fee.
Although i'm not sure how popular poloniex is anymore due to their KYC policies and lies, you could maybe try that..
(I personally can't really recommend poloniex though, and i would try to look for another more trusted exchange, although i'm not too sure if there is any other exchange out there which offers this..)

Because they might not want to give up their identities and instead keep their privacy, since almost every exchange that involves BTC -> USD & vice versa nowadays requires KYC...
