Please am trying to understand how the systems work that's why I need more clarification from you. I watch this cryptocurrency prices going up and down the axis but often times I ask myself outside the fact that when people made withdrawal it affects the price going down and when people invest high capitals it increases the price automatically but is there some kind regulators like human agents or electronic technology who always do the regulatory price actions especially when trading bitcoin? Or is totally program that way? Only your views please.
