how can i double my coins quickly?

There's no way to double your bitcoins quickly not unless you win from gambling.

To be honest you can't earn 1 btc out of no where and most of the ponzi schemes are scams so don't invest any money trying to double it in one night or so. It could harm you. I ensure you you will lose money.

Be careful about those investment schemes that will take the advantage of the high price of bitcoin and will encourage people to invest into their scam by saying sweet words.

It is easy if you have any skill or any knowledge, you should just try to search for the right job that fits you and you could earn a lot more then a bitcoin.

Even having the combination, it is still not easy without proper application and execution.
