Congratulations! That is an amazing accomplishment! 10 MV in under a year!
I have hopes to make the same accomplishment, but it seems that it might take me a lot longer then that :P We'll see!
I am powering up all of my earnings and don't plan on withdrawing anything any time soon! I'd say keep powering up! I don't plan on withdrawing any earnings within my first year because I feel it will benefit me more in the long run!
