The BTC has great potential, it has grown tremendously and achieved tremendous achievements, what it has achieved no other currency can repeat. It is the pioneer and the leader of all. No matter what happens, it will never collapse. Perhaps it is experiencing problems, but I believe we can solve it, an experienced king like bitcoin always knows how to overcome difficulties. Other currencies can grow and grow, because its technology is superior, but it can not replace bitcoin. I'm sure about that.
