Bitcoin is a form of digital currency and payment system.
It is created and held electronically.
It is a decentralised currency system so no one controls it. Bitcoins are not printed or minted like dollars or euros, they're produced by running specialized computers.
Bitcoins are gathered using software and super powerful computers by solving mathematical problems. The process is called mining.
There is no other better investment than Bitcoin that we know of. Your money will be more than 10 folds in 2 years.
So invest in Bitcoin now!
