Billionaire investor and Citadel CEO Kenneth Griffin has shared his perspective on the future of cryptocurrencies, predicting a shift away from Bitcoin towards Ethereum-based tokens.
The Next Generation of Cryptocurrencies
Speaking at the New York Times DealBook Summit on November 10, Griffin stated:
"I expect that in the next generation of cryptocurrencies, Bitcoin-based concepts will be replaced by Ethereum-based concepts."
He cited two key advantages of Ethereum-based cryptocurrencies:
- Faster transaction speeds
- Lower per-transaction costs
While Ethereum currently shows only marginal improvements over Bitcoin in these areas, the upcoming Eth2 implementation promises significant enhancements to both speed and cost-efficiency.

Skepticism About Bitcoin's Utility
Griffin has long expressed doubts about Bitcoin's practical applications:
"Bitcoin has no commercial use case. While blockchain technology is interesting as a decentralized ledger system, it's not the solution we need for most problems."
He raised several concerns about cryptocurrency implementations:
- Fraud risks
- High transaction costs
- Significant energy consumption
The Environmental Impact Debate
Griffin criticized Bitcoin's environmental footprint:
"Bitcoin's impact on global warming exceeds that of any traditional payment system we use today."
Key comparisons:
| Metric | Bitcoin | VISA Equivalent |
|---|---|---|
| Annual CO2 | 90.48 tons | - |
| Transactions per BTC CO2 | 1 | 2,008,657 |
However, it's worth noting that Bitcoin mining increasingly utilizes:
- Renewable energy sources
- Otherwise wasted excess power
Market Timing and Opportunities
When asked if he'd missed the cryptocurrency opportunity, Griffin responded:
"The train is still in the station in many ways—we're still in the early stages."
