For example, information about a digital coin's inclusion on the list of a popular crypto exchange or news about altcoin developers collaborating with a large corporation can cause its price to rise.

2.Large players can purposefully cause fluctuations in cryptocurrency rates in order to profit from ordinary traders' reactions.

Speculators take profits after waiting for attractive levels, and the trend reverses sharply. The majority of small traders lose money in such situations.
