After few years bitcoin price maybe $5000 or already replaced by other currency.
even if the price of bitcoin is 5000$ still not enough to replace the other currencies we all know,
if we accept bitcoin as a currency, bitcoin must have a fixed price.
A bit harsh but right because most of the people will not start using bitcoins.
Yes, stability is required for bitcoin to replace most of the currencies, but at the same time I love the price up and down because I earn with it with my bitcoin trading skills.
