I agree that fear is making people look over to the Crypto space, but I'd say that greed may be having a higher impact at this stage. People are looking at crypto gains and are starting to do the maths. Cryptos make any other "volatile" market look a long boring flat range, hence, very attractive to make more money. Especially when the dominant fiat of the country you live on it's taking a pounding (GBP here, pun intended).
So in addition to fear I'd add other 2 that are making cryptography popular:
- Speculation - Everyone wanting to get a piece of the action
- Increasing adoption rates.
And one is feeding off the other and vice-versa to cultivate ever more interest.
