Its quite interesting seeing people trying to compare altcoins with Bitcoin. In as much that BNB is doing good in the crypto market, I don't really think its gonna be the next bitcoin. There is no doubt that BNB has good potential in relation to its market volume, market cap and market value but there is no way its gonna be the next bitcoin.
Bitcoin is unique, nothing can compare with bitcoin. Let's take a wider overview. No one should compare Gold with other precious metals, and no precious metals can compare with Gold, that is one of the main means of exchange in human civilization. Bitcoin is the same as gold in that aspect, and it will become more widely accepted, and will dominated the crypto space for too long.
