In short Luna makes bad things worst.
Yes, the problems started much earlier and Luna only intensified the fall of the crypto market. Investors lost their appetite for risk due to high inflation in the US and rising food prices. The crypto-currency market follows the American stock market and positive news is not expected there yet. The situation on the market is critical and most likely it is not the bottom yet.
Actually market crashes are common in the crypto world, so this year is not the first time the crypto market has fallen quite deep.
So actually we don't need to worry too much about the current market situation, there are many factors that make the market crash.
Based on my experience of about 5 years of knowing the crypto world, price drops repeatedly occur, but the market can always
recover again. As long as we can be patient with holding good coins, and not selling the coins we have at low prices, everything will be fine.
However, I agree that what happened to LUNA made market conditions worse, so the impact of LUNA's drastic decline made many investors panic.
Because LUNA is known as top coins, some people think that investing in top coins is safe and doesn't have a big risk. It turns out that what happened
to LUNA shocked everyone, no one thought that LUNA could fall so deep, that's why investing in crypto must always be vigilant. Including investing
in Bitcoin we must always be careful, and prepare a backup plan of what actions to take if the market situation worsens. Because like what you said,
the current decline has not yet reached the lowest price, so we have to be really careful.
