I wold just say that i don't need anything which is not available to purchase with bitcoin. Bitcoin is money so i would spend and earn like it, I don't consider it as investment and wait for my expected rate.
Just convert or use bitcoin as it is, doesn't need to give any special privilege or underestimate it. If someone talks about legality
"don't be fooled with that scam", "it's illegal to have/use bitcoin" or other reasons.
I just pity them for having misleading knowledge about bitcoins, since he doesn't know the advantages and how easy it is to to use and transfer without hassle. Sometimes i try to educate him about bitcoins, but most of the time i fail.
as bitcoin is a private currency and you are the owner of the bitcoin you have in our wallet so you have the right to use it according to your wish, either you want to use it or store it or spent is in shopping, you have fully right for that and now one has the right to stop you from doing so and no one can claim for that bitcoin that you are owning. therefore people should not pock their nose in some one private affairs.
