Bitcoin wasn't created all of a sudden. The domain name was registered in August 2008. The planning was done over several years, and the work started well before there was any sign of an impending recession in the markets. Also, Bitcoin was already being mined during 2009-10, and it was during this time that the economic recession was at its peak. BTC broke above $1 per coin in 2011, when the recession phase came to a halt and the economic recovery started. From what I have seen, it is very difficult to link the major recession of 2008 or any of the smaller magnitude financial crisis (such as the Greek government-debt crisis and the 2012–13 Cypriot financial crisis) to the popularity of Bitcoin.
