You first have to figure out how many bitcoins you have. Let’s say you have 3 bitcoins. To multiply your bitcoins, you take the amount of bitcoins you have, 3, and mutltiply it by the amount of times you want to multiply your bitcoins by, lets say 10. Now the final step is to figure out the answer to:
3x10…
And the answer is….
30!
There, in three easy steps, you have successfully multiplied your bitcoins by 10!
TLDR: Don’t be an idiot and ask stupid questions, if you want to earn money, invest in projects (crypto currencies) that you think are worthwhile or just HODL your bitcoins and wait for their value to increase.
