Of course they are, the thing about P2p is that it's risky for newcomers, they will prolly find it easier/safer buying Bitcoin from exchange, than from an individual, cause as newcomers they would prolly not be abreast with security protocols, but other than than, P2p is great.
P2p can be risky for newbies if using an exchange that is not recommendable. In this regard, I am not implying meeting people physically that might result to physical attack, but referring to using p2p exchanges. Exchanges nowadays have made it simple, clearly stating it that before releasing bitcoin from escrow, that it should be ensured the buyer have paid. Which means the seller should make sure the money has been received and confirmed. Also, if the money have been paid, the seller should release the bitcoin from escrow, if not released within the time frame, the buyer can make a report. As for me, I prefer p2p to bank transfers.
