Just think, why on earth would somebody give hundreds of thousands worth of money for pennies?
They are most likely tampered, or erroneous, or the funds moved away long ago.
But as long as there are suckers buyers for this scam "business", it flourishes.

My advice is to stop dreaming and start thinking. Bitcoin is money. And if you want to get money, you have to get it like you'd get any other kind of money. If you see fairy stories, be wary.
