I guess it's a positive sign that bitcoin will rise again this year and maybe this time much higher than the last two years in 2017 because of the huge amount of volume of demand in the market.
I doubt that. Back in 2017, the situation was different. A lot of people, who had only vague idea about the cryptocurrencies jumped in to make investments. And these people lost quite a bit of their capital in 2018, when the prices crashed by 85% (or even more, in case of altcoins such as Ethereum, Cardano and Ripple). Not many of them are going to try their luck this time... so we need a new group of investors to push the prices to ATH. From where that group is going to come? One possibility is hedge funds.
