Here is the news from Coinfloor (UK exchange):
https://www.coindesk.com/uks-oldest-crypto-exchange-to-delist-ethereum-and-focus-solely-on-bitcoinCoinfloor, the U.K.’s longest-running cryptocurrency exchange, plans to delist ethereum next month, citing an unclear future of hard forks and the need for onerous technical support for the second-biggest coin by market capitalization.
The company will also delist bitcoin cash, the splinter currency founded two years ago in the aftermath of bitcoin’s heated scaling debate. Starting Jan. 3, Coinfloor will support only bitcoin, whose eleventh anniversary happens to fall on that day.
The plan comes ahead of the launch of ethereum 2.0, tentatively planned for early 2020, which will begin the process of shifting the network away from the energy-consuming proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS).
Coinfloor’s decision suggests that nurturing a team with the specific expertise to follow the technical trials and tribulations of coins like ethereum may be too expensive for smaller crypto players, particularly if this constitutes only a small part of their trading volume.
From the point at which it starts next year, ethereum’s platform upgrade “could take years to complete,” said Obi Nwosu, founder and CEO of Coinfloor. The complexity of the operation “means for a period of time there could be two versions of ethereum running.”
According to some ethereum developers, it’s likely to be years before the old ethereum PoW chain is fully merged into the new PoS network, leading to current discussions around ways to create a secure bridge between the two chains.
Developers really love doing all these forks - but they are a massive nuisance for everyone else. The exchanges, the online wallet providers, the payment processors, all of them have to do a shedload of work to accomodate these changes.
That's why I think coins that don't change much (bitcoin, doge) will end up being the winners. People just want something that works smoothly and that you don't need to do a lot of work to maintain, so that they can focus on the eco-system around the coin.
