Normal people still have little confidence in crypto currencies. What is the reason for that? First, the technology is based on complex cryptography that many do not understand, on the other hand, the total volume of the currently circulating Bitcoins and Altcoins is still low and price volatility high. This is an essential brake in particular for the development of many products based on smart Contracts.
Even if "pure" crypto currencies have advantages because they cannot be controlled by a central authority, it would be very helpful for a transitional period, if there were Altcoins, which are bound to classical currencies.
Such Altcoins can be realized with simple token Contracts for example in Ethereum.

For this you simply need people who are willing to literally burn their cash holdings in open fire or put it through a paper shredder.

How does this work?

Suppose, John Doe wants to put some EUR-bound Altcoin - EUR-Coins - into circulation. No problem - he has to collect 10 million Euros in cash and burn
