Well, we can say that the bitcoin is not failed, although the price now is failed or down, we can't say that it is failed then, however the price of bitcoin before is highest in value whereas the bitcoin investors can't buy because it's to expensive, but now they can buy bitcoin because they can afford.
Bitcoin failed as a currency, seriously I don't agree with this, few bad months doesn't mean bitcoin s totally failed. Still demand is there for the bitcoin and currently the price is stable not much fluctuations happening. On what basis one can say bitcoin failed as a currency need a strong reason to accept or else it just a rumor.
