Hello, so I sent some bitcoins from my multisig wallet to blockchain.info to participate in this ICO. I sent the bitcoins to the ICO and now I need to sign the payment but I have tried everything and it just won't let me find a option to sign it on blockchain.info. When I go to Settings->Addresses->Import Address and copy paste the from address from transactions it shows it as "Watch Only" and gives me the more options to "Archieve, transfer or spend" instead of the usual "Sign, show private key" etc.
Im really desperate been trying to figure this out for several hours now I can pay 50$ in bitcoins to whoever helps me solve this problem if they want
If you have successfully imported an address you will find the sign message option.
A bitcoin watch-only address allows you to monitor the balance and transaction activity at a specific address, but does not allow you to spend the bitcoins. Only the owner of the corresponding bitcoin address’ private key can spend those funds. By watching the address, you have read-only permissions.
Instead of entering the private key you have entered an address which you can watch only.
You can only access these funds if you have the private key stored elsewhere.
