Spot and P2P are two ways to buy cryptocurrency
On the exchange
there are several ways to buy and sell cryptocurrency.

Spot trading
Spot is a regular purchase or sale of cryptocurrency at market price.
When you buy cryptocurrency on the spot, it immediately becomes yours and is stored in your spot wallet.
Example
Price:
Ethereum — 2000
you buy 0.01 ETH.
After purchasing, this cryptocurrency appears in your spot wallet.
If the price rises:
2000$ → 2200$
You can sell ETH and make a profit.

P2P trading
P2P (Peer-to-Peer) is the exchange of cryptocurrency directly between people.
