It also seems to me that no one is precluded from having an "empire" on mining, since anyone can start mining. Perhaps this Jihan person has the most miners, but I would assume it is because Jihan invested a lot of resources into achieving these miners, which is also investing in the bitcoin network, helping to secure it and creating its worth.
The equation of X(mining) is profitable and Y(Jihan) is doing a lot of mining so Z(we must create something that disrupts that) doesn't make sense except if you were looking at it from the point of view that you wanted to find away to profit but didn't wanted to bypass the free market competitive process of also mining.
Mind you coming up with an improvement of the network or system that benefits everyone on average and finding a away to derive profit from that is totally fine. But the reason that X+Y should equal Z (from above paragraph) does not validate its usefulness or benefit to the community.
Please show me anywhere that I am wrong, I definitely won't pretend to see all the ins and outs of this. But please refrain from using unsubstantiated statements like:
Segwit/LN-practically everybody else would benefit. We can see now where BU is heading-linear increase of blocksize and fees. Maybe good for some near-sided miners (only in a short term), bad for EVERYBODY else.
BU=improvement from 14.4baud modem to 28.8 baud modem to 56k modem.
Segwit/LN/privacy enhancements=going from telephony to cable to fiberoptics equivalent.
...it is your job to read more on the subject...i am not writing a dissertation here on a message board post.
In simplest terms: linear increase the size of the block does not equal new technology, but segwit combined with LN does mean NEW technology, hence the comparison with modems vs cable/fiberoptics.
Re Jihan, please educate yourselves on "monopoly".
