seriously guys, everything you are asking has been asked a million times and we keep having to go around in circles explaining why none of that shit matters.  The only reason you want that info is to make yourself feel better about spending money.  

Did you give a crap when you bought your car and it depreciated by a third as soon as you drove it off the lot?  No, you spent the money because you wanted it.  

Not everything needs to be an investment.

And really, I put in 2.5 BTC not even giving a crap about ROI.  Maybe a couple of bitcoin is too much for some of you turds who needs to be coddled with random numbers on a word/excel document to feel "safe".
