BTC doesnt need to have any of the features your are talking about, its doesnt need flexebility or speed. It is Bitcoin in the end, all the alt coins you are talking about not only exist because of it, but directly derive their value and more from it. It is the backbone of the blockchain ecosystem, and I dont see even closely how it being is only getting started being regulated and adopted by masses and regulators or goverments going directly into stage of dinosaur extinction in over 2 years?? dude no ofence thats a bit over emotional statment , well at least basing on my subjective opinion. Peace wijuwiju. but generally I get what you trying to express, yet it ain't what you are saying in this post.
