If you have wondered why sites that give away free cryptocurrencies exist at all, here is the answer; Sites and apps that offer you a way to get free Ethereum make their money from advertising, and sometimes by using your CPU to help with their mining activities. They are also introducing you to cryptocurrency, in the hope that you will buy related services from them later.
Speculators have often pushed the cryptocurrency market forward by merely selling their crypto-assets for fiat profits. However, Ethereum’s budding ecosystem allows for money to be spent and earned within its own internal economy. Although we are still a long way away from maturity, once Ethereum scales, these positive developments will surely accelerate.
Bitcoin was launched in January of 2009. It introduced a novel idea set out in a white paper by the mysterious Satoshi Nakamoto—bitcoin offers the promise of an online currency that is secured without any central authority, unlike government-issued currencies. There are no physical bitcoins, only balances associated with a cryptographically secured public ledger. Although bitcoin was not the first attempts at an online currency of this type, it was the most successful in its early efforts, and it has come to be known as a predecessor in some way to virtually all cryptocurrencies which have been developed over the past decade.

Gold has had at least three millennia to establish itself as a store of value people turn to when social systems are in stress. Bitcoin has only existed for 11 years. While plenty of investors are willing to speculate on the possibility bitcoin might supplant or compete with gold, the idea is far from ingrained across society. When will it be more widely accepted? Perhaps when the international crisis of global leadership unleashed by COVID-19 undermines the capacity of institutions like the Federal Reserve to sustain economic and social confidence. Whatever new institutions and systems we create going forward will need to address how the internet has upended society’s centralized systems of governance. When that happens, we’ll need a decentralized, digital reserve asset as the base value layer. As I said, it will take time. Meanwhile, the developers will keep building.
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.
