money which the bitcoin holders have put into the system, and expect to get back from it ---
I've put dollars into bitcoin but I don't expect to get back dollars. I expect to get back goods and services.
It does not matter. If you buy 1 BTC today, the only way you will get 240$ worth of goods tomorrow is if tomorrow's new investors, after buying all the 3600 coins that will be issued tomorrow, will
also buy from BitPay the 1 BTC that you spent on said goods.
In time we will look back at the plentiful availability of these "new" subsidy coins. As time goes by those coin's will be harder to come by.
Hopefully merchants will continue to free up the coins they get from purchases and into the hands of those with understanding of how to resourcefully utilize this technology.
