What are pools?
Pools in cryptocurrency are like a shared “pot” where users deposit their coins so they can work and generate income:
- some pools earn from trading fees (liquidity pools),
- others support blockchain operation (staking pools),
- and the simplest option for beginners is stable pools, which contain only “digital dollars” (USDT, USDC, BUSD) and have almost no market risk
To perform any operation on a blockchain, you need to pay a fee — it’s called “gas”, and it works like fuel: the higher the network load, the more expensive the transaction.
Cryptocurrencies are digital money that exists only online and does not depend on banks. The most well-known are
- Bitcoin (digital gold),
- Ether (a platform for apps),
- and stablecoins (strictly pegged to the US dollar).
