I'd recommend sending coins to yourself at some point (literally just send coins to your own address) so that they aren't all broken up like grains of sand in your wallet, because if they are they'll stake one at a time.
I think this is not possible. A long time ago, I tried to send another coin to myself (same wallet) and the coin remained unconfirmed in my wallet for ever.
It worked for me... 133 confirmations on it but its up to you whether you do it... if you do, dont waste time or you may not be mature for growth period
