I love the idea of setting the currency supply to some lucky numbers. That's a better reason than some arbitrary "round number".
But remember that our plan is to display currencies in micro-percent (MIP?
**) so people can easily see their increase when a DAC pay's dividends.
** I realize that "micro" is usually a Greek "u" and "m" stands for "milli" , but did you ever try to pronounce uIPs? Maybe they could be pronounced "mikes"
So whether you pick 888 or 8888888888888888 or 4,000,000 as the underlying share supply it would be nice to get everybody to start thinking in "MIPs".
That means if you start with 40,000 XTS you would have 1 percent of the BitSharesX supply of 4,000,000.
That means you would have 1,000,000 micro-percent (MIP). So 40 XTS would be 1000 MIP and 4 XTS would be 100 MIP and 1 XTS is 25 MIP.
That way, transactions instantly destroy a tiny amount of the supply and everybody's displayed account balance in MIPs adjusts instantly upwards every block.
After people get used to this, no one will be interested in any other unit of measure - the instantly understandable unit of value will always be the MIP, no matter which DAC you are talking about.
