Well, first of all, there aren't millions

It is set to display the quantity in mBTC.

I am an infamous Bitcoin address containing 79,956 BTC stolen from MtGox in 2011, coins which have never moved since. Many claim me but no one has my key.
I assume that the whole wallet contains the same stolen bitcoins.
And yes, this wallet has not been hacked so far, so I doubt you can do anything with them.
So what recommendation do you have for me? Can I try transferring some of those funds to my wallet to see if it works or is it too risky to try? thank you so much
