@bigslimvdub. However, the fixed supply and the assumption that it is the better option is also a only theory. On bitcoin it appears that the effect is that is being used as a speculative investment more than a medium of exchange similar to gold. Early holders are incentivized to keep them instead of using them.
Aeon is a speculative investment since 99.9% of anyone who owns the coin are not spending it, only holding or trading.
Bitcoin is being used, integrated, and speculatively held on a daily basis. Bitcoin will also be around in its usable state until supply is exhausted, someone breaks sha256, or finds a severe security flaw that rendered the chain useless.
Most crypto coins with a tail emission could, and probably will, become obsolete soon after tail emissions kicks in and miners realize there is close to zero incentive to continue supporting the chain and it eventually dies off well before bitcoin can. The only way any cryptocurrency on tail emissions could survive was if the value increased exponentially to create financial incentives to continue mining operations. One of the reasons a specific project made an incredibly gigantic supply so it could literally never run out of supply in the developers lifetime.
