Thanks for the good comparison post!
I think Bitcoin will stay king for the next view years and if Bitcoin crashes (for real, not the „normal 50% dips) all other Cryptocoins will die along with it. The reason is that Cryptocurrency is still not really mainstream and if Bitcoin dies they also will. Bitcoin is such a big brand.
Bitcoin is changing its protokoll slowly and making shure the inplemented things work out in the long term, which is good. Increasing the blocksize and/or the blocktime isn‘t a longterm solution.
That's really encouraging! Thank you for your comment.
