I think its the greed of earning more money, new enthusiastic crypto investors and the old investors getting millionaires is what driving the bitcoin prices crazy now a days. I am always speculator who says that whenever there is some bad or good event is happening in the crypto world then there is always dependent bad or good chain of event curing. For example, there is fork, then everyone will think "wow we are gonna get free forked coin" and thus few starts investing money into bitcoin, the price starts rising and thus people start buying it crazy and it starts chain of buying. The similar thing happens when reverse is happening, the chain of panic sell! Now a days bitcoin is sky rocketing because of new people, merchants and miners jumping into it. Now everyone trust bitcoin and its ability to rise no matter what happens in the world and no matter what who bans it. This way we get financial revolution and hence more and more market.
