You could make the candle into a bitcoin storage.
Engrave a metal plate with a private key and place it in the core of the candle.
The public key (or QR code) should be on the outside of the candle so you can load coins into the candle.
Yes, the idea sounds complete stupid, it has one advantage though, a block candle can take up to 20 hour to burn down,
so this will give you some extra time to "cool down" before you panic dump your coins doing a dip or send them to primedice on a loosing streak.
This is awesome thinking mate absolutely awesome! As long as you have it in your bedroom away from anyone who may think about lighting it i could not think of a better way to store some coins for many years to come if need be. Not stupid at al and if it is i hold my hand up because i am going to look into this asap so thank you
