I wanted to send some bitcoin from my electrum wallet to another. The problem is that my wallet is in reading only and unfortunately I can't find my seed and I don't have my private keys. Is there any solutions for that ?
If you end up with watch only wallet it means you never actually have any control of the address that you listed over there. That's not a problem per se, your problem is how to relocate your seed or private key.
Isend send any bitcoins from my wallet. I guess I lost my bitcoins..
It is not possible to send any coins with that kind of wallet so I'm not sure how you did you spent your coins in the first place. If you have another wallet that you control and then send it to the watched address above then that might be the case. Make sure to double check whether the address is correct and for personal reason, do you have any control of that address or not. Sending coins to an address which you have no control over is essentially losing the ability to manage that coins.
