[mrandroid]

this might be a very silly question, in 2013 i mailed myself a 32 character string with the subject bitcoin, i dont know anymore what it is relate to, anybody can help?
it is formated like this:

476af129-7e54-7475-f1f3-e671a76c9312

it was in my wild days, so i have no clue if maybe i have a wallet or something dangeling around 
appreciate it, if anybody can shed some light on this
