Hello, I still do not understand the mechanism by which bitcoin or ethereum, or any other virtual currency, increases or decreases the price / value. It seems that Elon Musk is having a good time
Surprised because you are here on the forum since a while. Anyways, you might want to visit this thread for understanding how actually price rises and drops.
Check here and scroll a little bit, there is a very good explanation how Bitcoin's value is determined.
In case you want a small explanation: It is determined by the number of people willing to buy bitcoins/altcoins verus the number of coins being available in the market for selling. As the buyers dominate the sellers, price gets higher and once the sellers are more but buyers are not interested as much, the price will drop.
