Peer to peer, explained
On a peer to peer board you are dealing with another person. The exchange holds the coin while
the rupees move and releases it once both sides confirm. The price is better because nobody is taking a spread
in the middle, and it costs you a few extra minutes and some care about who you trade with.
Every exchange above runs its own escrow for exactly this reason. Your USDT is not released to the merchant
until you confirm the rupees have landed in your own account, not before.
Before a large trade
Check the merchant's completed order count and the limits on the offer. An excellent rate attached to a small
maximum is not an excellent rate for a large amount, and splitting one large trade across three merchants often
ends up worse than simply taking the second best price in one go.
