SPV wallets and mining pools are like apples and oranges β different things entirely.
SPV wallets are for handling your BTC, making transactions smooth without the full blockchain download.
Mining pools are where miners team up to mine together. You use mining software or hardware to join, not a wallet.
And yup, some pools have fees β they take a small cut of the mined Bitcoin as payment for running the pool service. Always check their terms before diving in! πΈπββοΈ
