My employer has offered to pay me my salary in crypto (BTC/ETH/USDC) but not sure if it's worth it in terms of fees.

I'd like to save part on BTC but will also need the money for normal spending in GBP. So far, I think that getting paid in fiat and buying BTC on an exchange is still cheaper.

Any tips or recommended services to take advantage of crypto by paying as little fees as possible? Maybe there's a solution I'm not seeing?
