This is one of the negative aspects of the lack of regulation inherent in the gendre. An initial stock offering (IPO) is a regulated procedure and the product has to meet certain criteria. Even at that the failure rate is high enough. So in the wild and free world of cryptocurrency it is not surprising that the numbers look like this. Even amongst the established “successes” such as BTC and Eth, the “value” is based on predicted utility. They are markets successes because there are buyers. Most of the “value” is speculative. It is far from certain that even these two giants will survive. If they do not it will be a great shame of course; and not just because many of us will lose money. Investing in Eth and BTC is a very high risk venture. Investing in ICOs borders on folly.
