Someone can say that price becoming very low is a marker of failure - you can accept or not accept that but of course the bullish lacking on that asset shows that lack of interest in it and therefore can be considered as a subjective marker only.
A developer being fired does not mean a project would fail. Someone will be hired again. Devs work for money - thats it. If they dont get paid, they will leave the project.
I myself have never been a fan of forks from bitcoin. But there many people who believe in them. I have nothing to say for them but to think differently and not to drown in their own misgivings but move on.
That's certainly true, mate. While forks cause some level of instability in the project, they indicate the level of democracy "baked" into the Blockchain protocol. People can fork as much as they want as the code is open and readily available for anyone to explore and modify to their hearts' content. But only those forks that are able to provide development, innovation, and real use cases for the mainstream world, will survive in the long run.
We're going to have to see whenever Bitcoin Cash's forks will last for long. We already have Bitcoin SV and now Bitcoin Cash ABC which forked off the original Bitcoin Cash project. The original Bitcoin (BTC) is still as vibrant as ever, despite being split into many factions. If you see it the other way around, forks with different visions and features are actually good for the development of Blockchain technology. Developers from rival factions can test out new features in order to provide people a choice from one coin to another. Those who prefer cheaper fees and faster transactions will find Bitcoin Cash to be suitable for their needs. Others will use Bitcoin (BTC) for cross-border transactions because of its unmatched security and reliability (despite transactions being slower and expensive than Bitcoin Cash).
Nonetheless, not every fork will turn out to become successful in the long run. The recent BCH community's decision of "stripping off" developer Amaury Sechet from the project may have dire consequences in the long run. That is if they're unable to find another developer that's able to keep the project afloat. The newly-splintered faction dubbed "Bitcoin Cash ABC (BCHA)" is struggling to get on its own feet. If it fails, the BCH community would have ultimately won. But if it gains traction, expect Bitcoin Cash to face fierce competition in the future. At least, Bitcoin (BTC) will continue to go on as usual thanks to its decentralized and open source nature. Whatever happens with Bitcoin Cash in the long run, will lie on the community itself. Just my thoughts
