Here is the reply that I got for Coinbase.com
Im not sure if by generation transactions if you mean newly minted coins? If that is what you mean, then yes, we do support them, but like any newly minted bitcoin. youll need to wait 100 blocks before you can transact with them.
I hope that helps! Let us know if you have any other questions, and thanks for using Coinbase.
That still don't tell me if it is good or not, now I started Bitcoin Core in pruning mode and again it is a lot a bandwidth, MY ISP allow me only 130 gig a month
Is there a alternative wallet ? I would like to go back to solo.ckpool
I'm pretty sure you could get by with a light wallet like Multi-bit and be fine. That still lets you control your coins, but you don't have to run a full node to make it work (IIRC).
I also contacted coinbase.com too and I asked:
I am planning to solo mine bitcoins, does our coinbase.com wallet address accept freshly found mined bitcoins directly?
and their response was:
We sure do allow acceptance of newly mined bitcoins. You can use any of your addresses found here to deposit what you have mined. https://www.coinbase.com/addresses
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?
