for me the big difference between bitcoin and other TOP altcoins is only community not the price
because all Top altcoins community is a part from bitcoin community right ? but not all bitcoin community will be a part from top altcoins community
that is certain, meaning the difference is meant about price,
if the price is clear about the demand and total supply that an altcoin has,
there are even altcoins that have a higher price than Bitcoin, namely YFI,
because the small total supply makes this fly past the king's price Bitcoin.
