Thank you for your comment!
The biggest cases of hyperinflation recorded have actually occured to normal currencies, backed by central banks, ministres and entire governments.
What in my opinion is interesting about the ICOs is that they fund technologies that can add a lot of value to the market. So I do not see them entirely as a substitute for normal money, but as an interesting way of funding technological improvements. There are thousands of companies listed in the stock exchanges, and no one says that there should be no more because there is not enough demand: the companies make IPOs because they need the funding to grow, quite similarly to the ICOs.
I like to buy shares of companies, and now the ICOs offer me a totally new way to get on board on exciting projects at its initial stages: it only takes one success to bring back the value invested in several ICOs, just as usually it only takes a wonderful increase in value of a stock to bring back what I invested in several companies. For example, the price increase in TSLA made up for the stagnation in the past few months of other stocks. So I am optimistic about the ICOs since we are fueling the future. =)
