Bought a few domains years ago from namecheap and I don't remember I used my coins to purchase anything else really. Maybe there were a few other occasions but I forgot. Bitcoin as a store of value makes more sense than using it as a medium of exchange anyway. Why would anybody spend their coins today if he/she can buy more of the same stuff for the same amount of coins tomorrow? Deflationary assets should be saved, not spent. If you are going to spend, spend your FIAT because it is losing value in the long term.
