This has nothing to do with the end of bitcoin, but about things that are going to cause problems for the regular investor. I have been thinking about this for a while. Before starting, I assume the price of bitcoins has been lifted due to speculation.

First, the people selling asic machines in return for bitcoins are going to destroy bitcoins for a period of time. Think as a seller. You sell a bunch of miners for bitcoins and let the people attempt to reap the rewards of mining. Once price rises enough, you sell out and reap the benefits before miners can. What perpetuates the price rising is early adopters who spread word of their earnings bringing in more people who want to get rich. In order to sustain the price and continue rising, you need more people to invest in the currency and believe in it. once influx of people come, this is where as a seller of machine i'd sell out or the next big wave.

It is the greed in which people want to earn money that will make this system fall faster because everyone will invest in miners and coins and watch them rise. Which it will, no doubt, but at who's expense? You and me the regular investor. It's the same in stocks or our own market. Remember this - when everyone believes they can make lots of money, that is when you get worried. All it takes is one bomb (mass sell off) to start and then rest of the disaster starts. As many investors tell you - MANAGE YOUR RISK.
