Most of the users have telegram here and they ask to trade there? Is this ok? Or it's more likely to get scammed when using outsource of the forum to trade?
No it is very riskly and you are likely to lose or be scam because you do not know the person outside this forum. So, better is use this forum and use escrow if possible, you will never be scammed. Keep in mind that this forum do not modearting any scam or possible scam.
