Exactly, I do not have any problem with bitcoin but I always spend them very fast. Because while I'm sitting on my computer, I can spend my bitcoins with 2-3 clicks. Normally, for paper money, I have to stand up my ass to my chair and go to a shop center to spend.
Yes, myself also do not find any problem with bitcoin. Bitcoin is already secured, fullfill all the terms for being a money and meaningful mining process. So, really I do not have any problem.
