There are a lot of different measures of value for a coin like XMR. There is the current value in btc on exchanges, there is the hopium value, supported by assorted conjectures and beliefs wrt the relationship between features (like a new GUI) and price, there is the ideological view of value, usually supported by assertions and beliefs wrt features a coin provides (like anonymity) and their perceived effect on future adoption and then there is the real value, which is somewhere just above the cost of producing a coin.

I mine, but not monero. I asked because I was curious how closely the exchange value in btc approaches the cost of mining at this time.
