You can refer on crypto market history graph chart and stop wondering why seems everything is going down because there are two things crypto market went down:
1. Every first to second quarter of the year Bitcoin, Ethereum and the whole crypto market doesn't really pumping and it all started to pump on it's third quarter upto before or end of the year.
2. FOMOs and FUDs, people are getting scared and afraid that crypto market will crash or would end due to fake news coming around.
This quarter is the best time to invest more on Bitcoin, Ethereum and Cryptos because everyone is expecting that almost all Cryptos would rise before this year ends.
