As we are heading for a new year 🎊 try as much as possible not to use your hard earned money to buy what will put you into a problem, avoid buying Bitcoin anyhow, Don't trust but always verify.
There is one advantage that centralised exchanges have, scammers who have stolen some Bitcoin don't come close to such platforms because they can be caught all because of KYC information, stolen bitcoin or bad bitcoins don't get sold on centralised exchange, they risk seizing or arrests, always use reputable exchanges.
Avoid peer to peer purchases from strangers because such transactions always lack oversight and transparency, making it a sure plug for scammers to sell their illicit funds and stolen Bitcoin, this gets me annoyed whenever I think about it, there are good people like me who cares about privacy and that's why we use services like conjoin mixers and others but bad people using this as advantage too is sad.
Be skeptical of unrequested offers via social media where you can be given a very good offer and sometimes too good to be true offers like Discount, yes you will get the bitcoin for discount but where the bitcoin really came from becomes your problem now which can land you in big problem later.
