There could be other factors involved too. Many NuShareholders purchased NSR for between $0.0018 and $0.0025, but didn’t pay in US dollars. They paid in Peercoin or Bitcoin that may have already experienced capital appreciation.
For example, let’s pretend User A purchased 3000 Peercoin in May 2013 for $0.20 each. By September 2014 his $600 PPC investment was worth $4500 once PPC reached $1.50 each. He then chose to purchase 2,500,000 NuShares (at $0.0018 each) with his funds.
His initial investment cost was only $600. As long as a NuShare is priced above $0.00024 (note that extra zero) he will come out ahead if he needs to sell. That’s why predicting the bottom based on buy-in prices isn’t likely to be very accurate. I think the market cap of NuShares is most strongly influenced by the number of expected future dividends shareholders will receive.
