I was wondering, if you had an opportunity to sell your stuff alike cars, pc, homethings and etc., would you sell it for bitcoin (or maybe other altcoin)? The main question is to see, are you ready trade stuff for cryptocurrencies and how do you imagine it?
It could be a good idea in the form of a centralized advertising service like gumtree.com.
Still they would have to figure out what to do with the volatility of BTC price, as today you could sell your car for $8,000, and the next day it could cost $10,000.
