A stablecoin is a cryptocurrency designed to hold a stable value, most often pegged to the US dollar (USDT, USDC and others).
In plain words
Stability is achieved in different ways: by the issuer’s reserves, by over-collateralisation in crypto or by algorithms, and not all methods are equally reliable. The risks: an issuer may fail to honour redemption, the price sometimes drifts from the peg, and for some stablecoins the issuer can technically block an address (it depends on the particular coin). The same stablecoin exists on different networks (for example TRC-20 and ERC-20), and you must send it on the network that the recipient supports.

Example. You are paid 500 USDT: on an exchange you swap them for hryvnia (for example through P2P) or keep them as “digital dollars”, choosing a network with an acceptable fee.
