Cryptocurrency market falls because all markets falls and situation in the world is very unstable too.
A lot depend how the world crysis will develop and how long it will last.
The condition of cryptocurrency market depends a lot of economical situation in the world.
When all market falls many people stop investing in all assets including cryptocurrency.
I don't think the crypto market has any effect on the world market, as yesterday during the pandemic season all markets fell, even the world market went down, but the crypto market on the other hand was getting better and better.
