In addition to the traditional trade in bitcoins and keeping them in order to wait for the appreciation, you can also invest in equipment for "mining" crypto currency. Each Bitcoin is a digital code for which specialized equipment is required. And the capacity of the equipment is growing in a geometric progression - in parallel with the slowing of the release rate of new bitcoins. Having invested money in the purchase of equipment, you can start earning your own bitcoins in order to subsequently sell them when the rate of the crypto currency will rise even higher.
