i have 5 btc
i want to double it
how i can make it 10 btc
If i had the bitcoins to spare then i would give you the extra 5btc if you could sign an addrrss showing that you even have 5btc because i think this story is bullshit.
If you had 5btc then you should know that it is not possible to double it easily.
How did you get the 5btc you say you have?
