Profit?
LOL great innovative idea you shared dude
i guess you should research the market on this as most of the things and products are already available with a huge range of competitors in the business. Concerning today's market yuo can get anything for BTC from a sex doll to a car so think unique and creative plus a heavy market research will have to play in.Just a suggestion i saw a thread selling customized cigarette lighters which was very impressive and good but they doesn't seems to be legit so i passed anyways consider this a suggestion. Shoot a pm anytime for support if you have a great innovating idea
Good luck
