There are numerous trends in the world of cryptocurrency. While it is evident nearly all of the major currencies rely on Bitcoin’s value first and foremost, there is also a period when that unwritten rule is thrown out of the window. Traders often refer to such a trend as “Altcoin Season”, even though most people will agree such a thing does not necessarily exist. There is a very fine line between what is perceived as “Altcoin Season” and “pump-and-dumps”.
It is safe to say no altcoin will gain value when Bitcoin is either bearish or extremely bullish. Although that situation can change over time, a bearish Bitcoin market will usually drag all alternative markets down with it. When the world’s leading cryptocurrency gains 5% in value or more, it takes a while for alternative markets to catch up. This is primarily because those currencies are losing value against Bitcoin directly.
