Interesting. What do you think of this (copied from near the end):
The key point to observe here, is that cryptocurrencies do have value,
but only as a transaction mechanism. Hereby the biggest bottleneck is prob-
ably the number of cryptocurrencies that merchants are willing the accept
simultaneously. However, due to their similarity, it is very straightforward
for e.g. merchants to accept multiple currencies. When we combine the value
with the relatively cost-less creation of cryptocurrencies, we see an equilib-
rium in the number of cryptocurrencies that is far higher than in the current
situation.
Inflation is impossible within the Bitcoin network, as well as within most
other cryptocurrencies. However, inflation in the cryptocurrency economy is
still possible, through an expansion the number of cryptocurrencies.
It is also through this multiplicity that wasteful mining will be limited. As
noted above, cryptocurrencies have value, because they are effective mech-
anisms for transactions. However, this is the only source of value. If a
cryptocurrency becomes too expensive (which causes excessive mining), a
new, lower valued, cryptocurrency will arise. Since the value of this currency
is lower, but it is equally effective in transactions, value will flow out of the
overvalued cryptocurrency and into the undervalued one. This lowers the
value of the overvalued cryptocurrency, and less mining will be done here,
reducing the waste.
In conclusion, cryptocurrencies such as Bitcoin have an enormous poten-
tial as a transaction mechanism, giving users control of their own holdings
and making transactions instant and costs negligible. Two commonly heard
issues with cryptocurrencies are deflation and wasteful mining. It can be
shown that these issues are not pervasive, when the cryptocurrency economy
as a whole is considered. Cryptocurrencies derive their value only from be-
ing an efficient transaction mechanism, if they appear to become overvalued
(causing excessive mining), other cryptocurrencies will arise. This will in-
crease the total number of cryptocoins (between all cryptocurrencies), which
will drive down the price, and limit excessive mining.
(Bolded emphasis mine). This statement assumes that people won't hold a higher valued coin but will move to the lower valued coin because of its transaction value, which is the only utility of crypto currencies in the author's eyes (as stated earlier in the article).
Thoughts? Cheers
