You think anyone would "print" their shares on top of a bitcoin that costs over $600 a share?!
Do you think it's impossible to print their shares on top of mBTC, that costs 0.6 USD?
Say we have a company with a typical 20 million shares out standing.
So if we go with you bitcoin solution using mBTC, it will cost 12 million USD to use bitcoin to distribute the shares.
What about an iXcoin solution using mIXC, it will cost 2,200 USD to get the IXC to distribute the shares using a crypto currency.
With bitcoin and iXcoin you can go down to 1 millionth of a coin ( the rest will be considered spam).
So let's go to to that level with shares. 1 millionth of a bitcoin is, 0.00065. 1 millionth of a iXcoin is, 1.1e-7.
20 million shares (no fractional shares) costs $13,000 for bitcion. 20 million shares of iXcoin costs $2.2.
Now we are talking about the price of bitcoin today, if bitcoin continues to go up, it would be uneconomical to use bitcoin for smart properties.
