Fake, you mean artificially created? Yes, but it is real people’s money.
First, you need to account all cryptocoins, not only bitcoin. IN one year, the total crypto market will be around 3-4 Trillions level, it can be more we do not know at this stage.
All cryptocoins are limited by its own open source and protected by block chains. It is basically demand and supply. People are/will be taking credit card loans, helocs, line of credits and buy crypto coins, many hedge funds are buying (already 125 funds).
Any thing uncontrolled and spiraling without real value is bound to fall and cryptocrash is imminent as republican government favors deregulation.
I foresee appx middle of 2019 we will have a cryptocrash if FED hikes four 0.25 before Dec 2018.
Prepare our self ready to take a deep breath for local real estate.
