In principle, this statement is generally correct. Cryptocurrency prices are constantly fluctuating: they rise and fall, being in the optimal range of support and resistance. This reflects the main principle of pricing - the balance between supply and demand.
Even now, when we observe the main cryptocurrencies - bitcoin and ethereum, we see that a certain increase in their price leads to a certain drop, after which a new wave of price growth sets in, which already leads to the formation of a higher price. High price volatility is the main difference of this market.
