Ethereum is another use-case for a blockchain that supports the Bitcoin network, and theoretically should not really compete with Bitcoin. However, the popularity of ether has pushed it into competition with all cryptocurrencies, especially from the perspective of traders. For most of its history since the mid-2015 launch, ether has been close behind bitcoin on rankings of the top cryptocurrencies by market cap. That being said, it's important to keep in mind that the ether ecosystem is much smaller than bitcoin's: as of January 2020, ether's market cap was just under $16 billion, while bitcoin's is nearly 10 times that at more than $147 billion.
DeFi’s ‘Agricultural Revolution’ Has Ethereum Users Turning to Decentralized Exchanges. DEX, often touted as a fairer and safer way to trade cryptocurrencies, might finally have its use case: yield farming. In the past, as Brady Dale reports, most people haven’t wanted to self-custody, preferring institutions to manage the risks of holding their keys for them. But in DeFi, where people undertake dual borrowing-and-lending schemes to make big, quick returns on incentives and high interest rates, is better if you control the keys during the trade. And decentralized exchanges are seizing the opportunity.
Though it’s too early to know who the eventual winners will be, I believe this trend captures the early beginnings of a new, decentralized global financial system. So to describe it, an analogy for the existing one is useful: bitcoin is the dollar, and Ethereum is SWIFT, the international network that coordinates cross-border payments among banks. (Since Ethereum is trying to do much more than payments, we could also cite a number of other organizations in this analogy, such as the International Swaps and Derivatives Association (ISDA) or the Depository Trust and Clearing Corporation (DTCC).)
That’s not to say there aren’t risks in DeFi. Many are worried that the frenzy around speculative activities such as “yield farming” and interconnected leverage could set off a systemic crisis. If that happens, maybe Bitcoin can offer an alternative, more stable architecture for it. Either way, ideas to improve DeFi are coming all the time – whether for better system-wide data or for a more trustworthy legal framework. Out of this hurly burly, something transformative will emerge. Whether it’s dominated by Ethereum or spread across different blockchains, the end result will show more cross-protocol synergy than the chains’ warring communities would suggest.
