It's better to be patient and wait until the market drops again. Today the crypto market is increasing. You should be able to do research before you decide to buy the coins you want. In red conditions, it would be better to invest.
How much should it drop in your opinion before you would suggest to invest? And what if it doesn't drop again significantly? If you think crypto has a future why don't invest now after the whole market dropped by 80%? It's very hard to hit the bottom with your investment.
