There are legitimate concerns about security on Ethereum. With such a complex system, and so many different programs running on it, the attack surface is large. And given the challenges the community faces in migrating to Ethereum 2.0, including a new proof-of-stake consensus mechanism and a sharding solution for scaling transactions, it’s still not assured it will ever be ready for prime time.
Decentralizing Everything with Ethereum's Vitalik Buterin | Disrupt SF 2017
Unlike earning Bitcoin online currently, there are only a few legitimate ways available to earn Ethereum since Ethereum is younger than Bitcoin and yet to reach more people though it is the second most dominant cryptocurrency even if Litecoin is called the predecessor of Bitcoin. Some sites have started to pay free Ethereum and we can expect more sites to pay Ethereum for doing online jobs like taking paid surveys, completing tasks, & offers, etc. For now, there are only a few ways to earn Ether online. More ways to earn ETH will be updated once they are tested and found authentic.
Decentralized exchanges (DEXs), which allow peer-to-peer crypto trading without centralized exchange (CEX) taking custody of your assets, have integrated WBTC into their markets to boost the liquidity needed to make them viable. Sure enough, DEX trading volumes leapt 70% to record highs in June. (It helped, too, that June saw a surge in “yield farming” operations, a complicated new DeFi speculative activity that’s easier to do if you maintain control of your assets while trading.)
I like POW (proof of work) crypto currencies where the system is ruled on the basis of how much computing power you can apply to maintaining the system. I’ve steered clear of Ethereum because it is heading towards POS (proof of stake,) a system where oligarch-sized owners of the coin get to call the shots and likely do what oligarchs do best, poop on the little people and fight to the death amongst themselves. Crypto is politics in software form, so to me the political framework of cryptocurrencies is all important. The POS future for Ethereum is a killer for me long term, but right now it is not that “in the long term we are all dead” that is the key, it is that visibility of the long term itself is all but dead.
Demeester, an analyst and co-founder of crypto investment fund Adamant Capital, announced last month that he’s scaling back his public involvement in Bitcoin. But his recent statement doesn’t mean he's shifting wholeheartedly from Bitcoin to Ethereum. He’s emphasized that he’s still a Bitcoin believer, and retains plenty of reservations about Ethereum.
Like other blockchains, Ethereum has a native cryptocurrency called Ether (ETH). ETH is digital money. If you’ve heard of Bitcoin, ETH has many of the same features. It is purely digital, and can be sent to anyone anywhere in the world instantly. The supply of ETH isn’t controlled by any government or company – it is decentralized, and it is scarce. People all over the world use ETH to make payments, as a store of value, or as collateral. The latest news about Ethereum mostly concerns the move to Serenity the last post-development phase of Ethereum as well as changing Ether mining’s concept from Proof-of-Work to Proof-of-Stake in order to reduce the power cost of the process.
