How long takes Black Hat seo to work?

I want to rank in low comp niches in a month or two, is this possible?

I mean if i do full black hat i will get penalized with google before my site ranked (GSA,2.0s)
But if i dont how much will it take to rank with "Good Links"

Never Ever did Google Seo just Youtube and i want to start in something more serious
(Higher Payout CPA,Revsharing)

Like can i rank for multiple Low Comp long Tails in a month or two?

As much as I'd like to say; 2 weeks, 3 days and 19 hours, 4 minutes & 11 seconds...... I can't.
There's no defined answer, it could be as above or it could be 2 years.

Too many variables for anyone to tell you this. How good is your onpage? How good is your keyword research? How strong is your opposition?

A medium competition keyword would rank on page 1 within 2 months if the seo is done correctly. IMO it may take a month more to rank on top 5 ranking.

yes you can. But PBN is not any good idea for the future. Making some guest post and contextual backlinks can rank up your LSI keyword within 2- 3 months. Do it naturally yourself or hire someone to do for you. Buying PBN can penalize your Website.

It varies, I see some improvements immediately and others take ages.
