The best way to stay out of scams is to have only legit connections. Scammers usually reach out to their targets through ads, reviews, and tempting yet unexpected offers. As a trader, you need to know what is too good to be true. And always consult someone who has knowledge in trading.
The thing is, you prolly don't need any "connections" or so called "trading experts" to avoid being scammed, on the contrary, people have been scammed through acquaintance they made on the network, cause if you're not careful about the personal information you give out, notwithstanding how legit the acquaintance seems to be, then sooner or later, you'll run into scammers and lose your funds to them.
Having said that, in my opinion, what remains the best way to avoid being scammed is to do your own research into what the modus operandi of scammers in the network is, thus you'll be able to identify when scammers are trying to use it on you, you'd also have to keep your avarice in check, and also understand that really the things that look too good to be true is indeed untrue.
