It was not the intention to show that bitcoin has major flaws. Sorry on that.
Despite the flaws of bitcoin it managed to dominate the market even there are many other coins that is much better than it, why? because bitcoin already gained the popularity it needs to be respected and gross reputation through the years. I guess this is another FUD, well it really looks like FUD spreading because of the bitcoin gradually decreasing price right now. One thing is for sure, bitcoin will never be over.
