Hello, I still do not understand the mechanism by which bitcoin or ethereum, or any other virtual currency, increases or decreases the price / value. I don't know if it is a scam or not
Even though you might not fully understand it why the their precise increase or decrease, but for some reason you are here in this forum which means you most have something to do with crypto. So, it is all the curiosity for the ones that don't still understands along with the understanding of the expects that fuel the price if you get what I mean, profit making through Demand/Supply.
