I believe Aeon should consider changing its ticker from AEON to XAE to conform to the ISO 4217 standard for currencies, much like XMR (Monero) and XBT (Bitcoin, on some exchanges like Kraken).
I've already posted similar comments on other crypto threads, but here's my general take on this:- The code space for X** is quite limited with only two variable letters. This has worked fine with just a handful of codes like XAU and XDR, but it will be confusing if all major cryptos start adopting the scheme.
With only two letters the codes cannot be very descriptive. - ISO codes are mainly for national currencies, and as such represent the old world where only nations can issue and control money. In cryptocurrencies, we have a much improved system for the new world, and I see no need to pander to the old powers. "Please give me an ISO code, I want to be taken as seriously as EUR and USD which can be printed willy-nilly at the whim of governments."
While there are many crypto coins, the reality is that there are not many crypto currencies. At this point the majority of new cryptos are not currencies but tokens for smart contract systems and various things like that. Currencies like Bitcoin, Litecoin, Monero, and Aeon, are quite different from tokens like Ethereum, Sia, Counterparty, etc. In other words, there isn't any reason for these tokens to use a standard meant for currencies, but since Aeon is meant to be a currency it should probably consider adopting this standard.
I don't disagree with you that there isn't a need to conform, but I do think the standard is nice and gives an air of professionalism to the project.
A four letter ticker doesn't look as nice in my opinion, but of course if people prefer it then that's perfectly fine too.
