Cornell University professor Eswar Prasad wrote a piece earlier in the New York Times on Bitcoin, triggering a huge backlash on social media.

I posted on it here: "The Brutal Truth About Bitcoin" (includes link to his article if you are interested)

CNBC have an interview with him, he has highlighted what he sees as 3 flaws with Bitcoin:

1. Bitcoin mining is energy-intensive, as is the process required when transactions are validated on the bitcoin blockchain, .... is "certainly not good for the environment".

  • he recommends Ethereum as it requires less energy

2. Says it does not offer anonymity:

  • "if you use bitcoin a lot, and especially if you use Bitcoin to get any real goods and services, then it becomes possible eventually to link your address or your physical identity to your digital identity."
  • highlights Monero and Zcash as alternatives

3. Doesn't work well as a currency as it's "slow and cumbersome" to use bitcoin to pay for goods and services, and the market is very volatile
