The lack of dev consensus in BTC is killing it at an amazing rate.....at some point market share will be lost if this continues and why would people switch back.
The big implication being if BTC can not even decide on this issue, what about all the other issues that are going to come up?
I wonder when BTC community is going to see this? Before it is to late?
DASH is also kind of irrelevant, just because their market cap is still well under a tenth of Bitcoin's.
Ethereum is definitely getting somewhere but it's on its own path. Even if it's price became higher than Bitcoin, it wouldn't have taken Bitcoin's place - it's tiny centralised development team shows its separation from any communities associated with Bitcoin and Bitcoin wouldn't die.
But Bitcoin could potentially die from itself (rather than the rise of altcoins). This would only happen if the debate went on for more than another ~8 months without a solution and the cost of transactions kept going way up. Even then I don't think it would ever die, just suffer.
