Yeah, the same thing happens in the crypto-currency market. When no one is talking about a particular cryptocurrency the price may be low but when people start talking about it the price will be high. Those who buy when there is less demand will make more profitThe fact remains unchanged, i believe it's obeying the law of demand and supply that state that. The highter the demand the higher the price, and vice versa. Make sure you always buy things when there's less demand.
