OP, your title is a bit misleading. I rushed in here thinking I was going to read about the different types of scam only to get "Guides to avoiding different bitcoin scams"
Maybe you should consider changing the title to a more fitting one
Yeah, it's a little clickbait, the content is more like "Don't do this unless you want to lose your coins.
And the advice is pretty generic, all of them can be replicated for some fiat payments methods also.
this is the obvious scam but the less obvious one that is common nowadays is the cases where they tell you they can help you "make profit" is an investment in some shitcoin they want to pump, in other words they don't take your bitcoins directly to their wallet, they instead take it from you indirectly by encouraging you to buy their sell orders of the shitcoin they want to dump!
they disguise it in form of "investment groups", or "signal channels", and things like that.
The sad part is that once somebody builds a website, posts some fake profiles and pays a few hundred of dollars in advertising people start taking the bait. The howeycoin thread shows how gullible people are.
Greed is the biggest enemy and with all the exposed scams, people losing money, all the information available, they keep handing money to unknown persons hoping they will become rich overnight.
