Woah that https://www.blockchain.com/en/btc/address/1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF?offset=250&filter=6 address is filled with $300 million!
I thought this whole riddle was about 32 BTC?
Btw I am not into this cracking kinda stuff enough to participate into this. Just clicked through the posted addresses in this thread and found this HUGE wallet which a user above me posted.
 
Insane.  
I guess if this key is crackable, the reward is so insanely high because it is nearly impossible to crack.
I'd love to know the guy knowing the result to this riddle and get to know how to solve this lol. That'd be awesome.
Like "Hey dude you heard about this riddle I made with Bitcoin? You aren't into BTC anyway, so here's how to solve it...."
"Oh that sounds fun! No worries I won't participate in solving it. *Opens Bitcoin wallet and imports priv key*"  
 
By the way: Ever thought of where this huge stack of Coins might come from? Could the source be some illegal hacking stuff offering the coins for grabs via a riddle because they can't sell them anyway? (IF it is related to any riddle at all.) Could it be an exchange wallet not related to a riddle at all? Would be really interested in seeing some blockchain analysis here to get to know who owns/owned these coins and how they have been acquired. 2011 is a long long time ago.  
Or did Mark Karpeles forgot a paper wallet sitting in between his couch again?
