Why did litecoin manage to get SegWit so fast while bitcoin is still slow and painful.
Activation of Segwit depends upon consensus of miners. In case of LTC, all the number of miners were low and all of them were in favour of change (including founder) so it was pretty easy to apply.
But in case of BTC, number of miners are too high and everyone have different opinions. So if Segwit applied half heartly at 50-60% consensus, it may leads to opposite circumstances in BTC ecosystem like we see in "Democratic Countries regarding Government ".
"Democratic Countries regarding Government " nicely said, explains why sometimes things move faster at not so democratic countries *cough*
That's what I am saying. In non-Democratic countries you have nothing to do with public consent, all you need to do is set a policy and people have to follow them. But in case of democratic countries you have to look after the view of every person. That's why decision don't move faster. Similarly in case of bitcoin, Segwit activation is difficult because we have to look after views of every miner.
