what is the average price of 1 ESP? (BTC value, screw LTC)
There is practically no btc market for it.
Whatever ESP was ever sold, it was at 1 sat. Actually, maybe 2 sat for some very small trades on small exchanges, if you are lucky and fast in depositing.
But there is no regular trading, just huge amounts sitting on offer at 1 sat. The only real market currently is ltc and it usually goes from 40 to 70 lat, with a few exceptions on either ends.
Unfortunately the 10:1 decrease in supply only changed price accordingly (from 4-7 lat) without any added value.
I still hope that will change, after the functionality updates take place (which seem to be taking forever).
