Developers said in whitepaper that they need min. 750 000 USD for the job to start. And it`s quite realistic goal. I don`t get where "InvestmentKenny" found the amount of 87$ mln.
$87m is to have a target 1 satoshi price level for SPRS to be traded on exchanges based on current BTC price levels, not the minimum refund investment.
Maybe tradable only with ETH at start then ? (not a good thing)
Still... the amount of coins for this tech is massive. It makes sense from a end-consumer point of view, but regarding the exchange/mcap/ico limitations.
