You may be right. Most likely it will be so. Although it may not be in such an explicit ratio of 90/10, because no one knows what coin will remain, and what is not. All these changes are in the power of time and demand. If the coin is not in demand, sooner or later it will die. This applies not only to the crypto-currency market, there are such market laws all over the world. Here is no exception. Survival of the fittest, that's all!
