It read: "sknab roftuoliab dnoces fo knirb no rollecnahC 9002/naJ/30 semiT ehT”.
Complete gibberish right? Well someone eventually cracked it. However I have tried to do some research on who this was but I haven't yielded any results. The general consensus is that this message translated into:
“The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”.
It took roughly 10 years for this to be unscrambled and made sense of with several experts said to be on the case. I'm unsure when the message was first discovered and when work commenced. As you can imagine this took a very long time but probably didn't take as long as 10 years. It probably went unnoticed for a few years.
Interesting, so for 10 years we don't know that we only have to read the code backward to find the message.
I don't think it was a difficulty thing but rather the message existed. I'm not sure when the message was first discoered because the forum doesn't yield any results when I search for it. But I think a few people were talking about it back in 2013. I think the OP is wrong and the code was cracked at a earlier time than 10 years. Bitcoin was created in 2009 and therefore the date would have to be 2019 so I am 100% sure that the code wasn't discovered recently. I think it did take a few years for someone to notice though.
