I think the only was the price will start to rise is by having more people buying it. Simple as that.

Why should people buy cryptocurrency? Not everyone knows how and wants to trade cryptocurrency on the exchange. What other area of bitcoin application do you know? Many people wanted to protect their savings from inflation and tax authorities. But recently, governments have taken enhanced measures to ensure control over the movement of cryptocurrencies. The exchanges support the governments in this. I think the demand will continue to decline.
