If you want to transfer crypto without fees, you can use a cryptocurrency such as Nano (XNO), which has zero transaction fees. There’s also many other cryptocurrencies such as Solana, XRP and Stellar where fees only cost fractions of a cent.
Another thing to consider is that you can sometimes send crypto with no transaction fees if you make an internal transfer on a cryptocurrency exchange. Check with your cryptocurrency exchange to see if they charge any fees on internal transfers between accounts.
