There has been an influx of 600.000.000 fresh $ to the crypto market within the past days.

The entry door is very likely through Bitcoin. Given the current trading volumes, it is not crazy to suspect that up to 50% of this money is supposed to be traded into Monero.
Therefore we'll see a market cap. decline of Bitcoin somewhere around the $300 million range. This money will go into Monero within the next days. Let's just assume that a lot of profit taking will be going on.
Still it's more likely than not we'll end up somewhere around $20. And this is just the potential with the current money in the system.
I see no reason to be bearish within the next weeks.
The influx would be several magnitudes below the nominal market cap increase.
