Ironically a lot of people that would have before criticized Wall Street now seem to be spending more effort criticizing cryptocurrencies ? (Even though they are the same kind of people that created and popularized cryptocurrencies to deal with Wall Street's issues in the first place ?)
Indeed, one good criticism of cryptocurrencies is that the are sucking up a lot of the attention and money that could go into actual reform.
For example, contrast Bitcoin usage in emerging markets with something like M-Pesa. They both started at the same time, but M-Pesa has been a huge boon to the unbanked, whereas Bitcoin is a rounding error in those markets.
