Those are good points you just outlined above regarding measures to preventing scam generally, but however, when it comes to the crypto space, i think the measures of avoiding scam are a little bit much deeper than usual, most especially the common p2p scam that have been noticed going around for a few months now, whereby p2p vendors will deliberately cut your payment and claim it was a mistake, and in such scenario, if you are not alert enough to confirm your payment before releasing fund, you tend to lose that money that may have been cut off. Hence, it's advisable people always confirmed payment when using p2p before releasing funds, because it is the most common crypto scam going on this period.
