What is block in bitcoin system ?
I am using bitcoin since 2014 but still i don't know what block is
OK, that's easy: Blocks are the parts of the
Blockchain (explanation at Wikipedia)It's impossible to have two Bitcoins running at the same time. XT, Unlimited and all other formed sides are nothing more than altcoins.
Both can claim that they are "the real Bitcoin". To my knowledge there is no globally accepted Bitcoin trademark (except for one in Russia).
We just need to be patience when it comes to the activation of segwit. I know it might take a while, but at some point something needs to be done in order to push Bitcoin to the next level.
I agree. I'm hoping that the Segwit activation in LTC could drive some miners to accept the Segwit proposal in the future. And perhaps Core devs could make a move and increase block size at least to 2 MB to convince the Chinese miners that oppose the current limitation.
Ehh it doesn't worth like that. You can't put Unlimited, XT, BTCfork or whatever in a single package. Those are separate blockchains.
No. If Unlimited imposed itself finally as the main competitor to Core, then the other "big blockers" would switch to Unlimited. There would be no point of using XT, Classic or other fork. But it's still possible that a more moderate proposal would "win" the big-blockers competition (like Classic).
Nobody is going to support anything but Bitcoin Core anyway. If it ever happens it's a good opportunity to double your bitcoins by dumping your Unlimited or whatever.
That's a possible outcome, but only if Core offers real usability to its users. A 1-MB-Blockchain won't offer this in 2018, even with Segwit activated there would be probably worse bottlenecks than now. So most users that want to use on-chain transactions would switch to Unlimited.
