Hello. I know only passphrase, dont know which wallet, dont have wallet.dat file. Is there is any chance to recover my bitcoins only with this passphrase ?
If you don't have the wallet.dat then you can't able to recover your wallet.
Do you still have the PC/Laptop where you installed the wallet?
Maybe you can still retrieve deleted wallet including the wallet file from your laptop/PC if you accidentally deleted it before.
The passphrase is just a password anytime you can change them unlike backup wallet.dat, seed, or private keys if you have one of these then you can able to recover your wallet.
