I think Bitcoin will lead the way for a few years. It was the first crypto and for now it is the one that people turn to when they see no honest alternative. However, like all technologies, Bitcoin will be replaced by more efficient and more larger scale alternatives. That is inevitable - the public (and industry) will follow the path of least resistance. This may be Ripple or maybe some other coin with fewer hang-ups like NEM. Who really knows but my feeling is that it will be a coin that is also accepted as a mode of transfer by all the major banks and Ripple is certainly looking like a viable candidate
