Bitcoin was created in the wake of the 2008 financial crisis... so does that mean that people will flock to cryptocurrency if there's another one?
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 201213 Cypriot financial crisis) to the popularity of Bitcoin.
Therefore, the impact of the global economic crisis on the price of bitcoin, we can fully see only at the next such crisis.
As for Putin and his dissatisfaction with the fact that the international community is adopting economic sanctions against Russia, in this case only he is to blame. His foreign policy, and especially relations with neighboring states, with whom Russia was previously part of the former USSR, is largely based on military force and aggression. For such robbers and pirates, there is a place in hell where he will no doubt find himself guilty of the deaths of thousands of people both in his state and in Georgia and Ukraine.
