Many traders prioritize profits in a short period of time, when the coin rises they will sell gradually with little profit but safer, the daily trader must think more fortunately a little less as long as the risk of dump can be avoided, dont be greedy..
Yes right, when there is a slight increase, they sell immediately, this is what makes the difficult market skyrocket like what happened in 2017.
But in 2017, as Bitcoin was increase, people were selling at every increase and yet, it still kept skyrocketing, I am not sure the slow movement of price is as a result of traders selling, I think the reason for it because we have seen not seen more big time investors that will put in large sum of money, look at the investors we got early this month.
Despite the fact that people are selling, it is still maintaining the price they pushed the value of BTC to, so we need more of such people consecutively to be able to achieve the ATH of 2017 before thinking of going beyond it, once we get big investors, the price will surely skyrocket.
