we've heard a bunch of times about fiat money and escalating problems. any reason for bitcoin to decline rapidly and all the online wallets closing down how will everyone fear the loss of bitcoins. It can happen because its the problem with real money its causing bitcoin to get blocked halfway.
I would think that just the opposite of what you're saying would happen. People would be attracted to Bitcoin because of the economic crisis, and Bitcoin could be an alternative to gold and silver for the more tech savvy people out there.
This is already happening on a small scale.
