It's not scary, and by looking at your comment history it's pretty obvious you have an agenda against Bitcoin, and you are trying to promote your PoS (a flawed concept) altcoins, probably just because you can't stand that someone else invested in Bitcoin before you. Apparently 1,000% gains per year is not enough for some people.
Interesting let stick with the 5 pool controlling the network part, and cut the crap with my comment history it is irrelevant. Start by addressing why is not scary. Just saying it is not scary it is a pretty stupid explanation...
