All i know is bitcoin is the only one thats increases its value,and this women who gives happiness in just a little bit of time also increase thier price. 2.5btc is a lot of money they dont deserve that price, 0.1 btc is enough for them.
After a couple of last tricks of my wife, I do not know what price you can evaluate. True, she generally got the gift and I did not have to pay for it at all.
