Considering there are thousands of coins and tokens out there, what sort of dominance should Bitcoin have which shows that even though it remains the dominant force there is still a lot of space for others to narrow the gap?
Currently the BTC Dominance according to CMC is: 62.6%
During mid-2017, the dominance was down to 33% and Ether was closely behind with 31% (BTC lost a large chunk of the market share when BCH forked out). But even then, Bitcoin was the most dominant coin out there. Now the market share has grown by almost 2x from those levels and we don't need to worry about the future of Bitcoin anymore.
