So I am taking that as a yes that coinbase.com wallet address are safe for solo.ckpool.org? Or to be really sure, anyone solo mined with a coinbase.com wallet address that hit a solo block from solo.ckpool.org want to verify that they received their coins and nail this once and for all?
Do you guys not have computers at all? Anyone mining should have their own wallet. Period. Not some rent-a-wallet from some online supplier that can just take your coins and claim "Oops, dey got stoleded. Srry!". Run Multi-bit and it takes about 8 mb of space. Run Bitcoin core if you have space and bandwidth to run a full node, then use Armory for a secure wallet. It's not rocket science.
while you can make the core wallet very secure.. i believe for the most part an online wallet is more secure then most people.. meaning they usually force 2fa from authy, and they have sms text withdrawl. core wallet doesnt do that, and lots of people choose stupid passw0rds, or not backing up in case of hardware failure..
so i do think that an online wallet is probably better for a regular person.. (read that i lost 21 bitcoins thread in general)
now i would NEVER hold my coins in an exchange.. those use hot wallets and your coins are pooled up.. not kept private.
id use blockchain.info.. and id use a pregenerated address.. meaning i generated the keys from somewhere OFFLINE.. you can use a program or a wallet from a computer that is NOT ONLINE.. then import it into blockchain.info manually.
this will let you use online security.. but at the same time the key was never ONLINE so nobody can hack it. plus if for whatever reason blockchain.info goes down, you can import that key into another client and still have access to coins.
