I am sincerely sorry that I cannot agree with you. Bitcoin will never be replaced by a coin. Bitcoin Gold is no longer the position it started in the market. You can easily understand that by looking at the graphs of the last few months. I do not think anything could be next bitcoin, nothing is like bitcoin, not even ethereum, but could this thing make some people some money? Well of course, so many coins went up in the but BTC will rule forever in my opinion.
