Guys anything with Tamper Monkey is a scam

Please provide further details In support of your claim.

If need be, I can take action accordingly thereafter.

I believe he's fair in saying that if the guide instructs you to use Tampermonkey, it's a scam. In the past there have been guides that instructed people to use Tampermonkey, in an attempt to steal BTC.

Whether the guide includes that instruction, is another matter.
