I totally agree. I'm confident a crypto coin crash is coming to eclipse any we've had before. The combination of volume, transactions/second limits, and weak exchange infrastructure; when people want to get out things are going to get ugly.
Worse, the people buying in now aren't true believers. They are "investing" because they think it is easy money. These folks represent a larger percentage of the market cap and are also least likely to have confidence in bitcoin for it's utility. They also stand to lose the most because their buy in point was so much higher. (people who bought in at say $1000, are just losing profits)
A panic sell will happen at some point.
As Bitcoin becomes extremely mainstream, those who hodl Bitcoin with religious fervor are increasingly becoming a smaller minority. Eventually it’ll reach critical mass and there will be enough disloyal Bitcoin ownership to cause a panic at the first significant sign of selling.
Once the bubble burst then no one argues that they were in a bubble.
