When bitcoin price increasess, altcoin decreases. When bitcoin price decreases, altcoin decreases as well. In both case, altcoin suffers. When does altcoin price increases? Why market follow this behavior? Please share constructive reason behind this.
I think that simply the price of Altcoin increases, is when Bitcoin is in its Bullish trend stage.
The reason is that at the moment that Bitcoin begins to increase, at some point there is a setback or correction, and therefore at that time altcoin suffers a slight decline, but many Bitcoin investors know that they are in the Bullish trend phase and they buy Altcoins immediately, but against their BTC pair, (Alt / Btc), for the simple reason that it will continue to increase and they multiply their investment, because Alt is cheaper but as the trend continues to grow, it also increases, always respecting Alt / BTC.
And this happens because Altcoins depend directly on Bitcoin. That is why when the bullish trend is identified, investors pass all their FIAT money to BTC and invest it, as it was seen in 2017 when it was between October to December, most Altcoins were painted green.
