Here is the reply that I got for Coinbase.com

I’m 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. you’ll 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
