Without key can we assess coins on wallet

[CrossroadBTC]

1. If the wallet you are using is controlled by a centralised entity then it is possible that you can recover your coins because centralised platforms always have access to all their uses assets, for example free wallet or coinbase

2. If the wallet you are using is a decentralized wallet, meaning when you opened the wallet you are giving recovery seed or private key this means the wallet is decentralized it might be open source or closed source it doesn't matter but once you lost access to either the recovery seed or the private key it's over

Once you lost your private keys, forget your crypto assets forever. That's why it's always advised when creating a new wallet address to write down your private keys on paper not by storing them or screenshots.
Private keys are like access to a locked door. Once forgotten or lose, you gat no access to it ever again.
