Is it possible for Bitcoin to fall to zero or be replaced by another Cryptocurrency?
We may see some unexpected events worst than the 2018 or any other bearish year. But I doubt it that we'll get to see bitcoin go to the zero.
Replaced by a new crypto, it wouldn't be a crypto but likely the governments counterpart.
But then again there are still people who will continue to support this market, those who are believing that bitcoin
will be here to stay, there are many circumstances that may affect the growth and development of this alternative
currency but as long as there are people who continuing to believe value won't turned to the point that it will be
worthless at all.
