So according to this graph, I buy $200 worth of bitcoin today and wait to the end of 2015 to get at least 30,000 in return. Nice. Why isn't everyone rushing into this?
Poor people should buy $6 worth of Bitcoin, at the end of 2015 they'll have 1,000
Below-average income people should buy $60 worth of bicoin, return of 10,000
Good-income people should buy a Bitcoin, return of 100,000 by 2015.
Carlos Slim should buy 6000 BTC, he'll have 600,000,000
Satoshi could have 1,000,000,000,000.
The reason is the same as when people were not buying Litecoin at half a penny in 2012. The price was depressed and that drove people away.
The same is right now. When people lose money by making bad trades they are forced to find another means to make income they lost and that usually is in the form of a day job. So they leave the community to focus on their financial well-being and then return when the news sites are saying "Bitcoin just hit $5000"...then the cycle repeats.
Most people who have money to invest do not invest until the market is already going up.
My attitude is stay the course if you can afford to. But make sure you do your homework before investing and make your own decisions.
