At the end of all this, once true markets develop that offer products with utility, I don't see how we have more than 3 - 4 functioning cryptos with appreciable use. We have 3 - 4 main credit card companies (Visa, MC, Discover, Amex), 1 main payment system (Paypal), and I'm sure I could think of other industries that have settled on 1 - 4 main players. I just don't see room for more than 3-4 cryptos maintaining today's elevated market caps, and the ones that do would likely go through a crash before reestablishing themselves.

The bottom line is that neither little old grandmothers nor I want to convert our cryptos into one of the 1'000's of cryptos out there used by any particular company. We want something like Paypal, with a single system that is universally adopted. This is not just for ease of use, but also to maintain the value of crypto's (remember, one large impetus for their creation was all the QA being done by central banks).

There is one way I could see having more than single digit cryptos in the long run ... if each country or region has their own crypto unit, pegged to their local currency. But if this occurs, they are weaker as a store of value impervious to central bank manipulation.

Ultimately, I'm hoping that 3 - 4 cryptos rise to the top over the next half decade, and I am lucky, insightful enough to have purchased one of those four.
