I suggest to refrain monitoring the market for a while, that way you dont need to stress yourself from too much thinking. Anyway if you know what you're getting into before investing in crypto you wont question if its already the end since you are aware of the risk.
It's not about thinking negatively, it's about thinking illogically. The end of crypto, while not impossible (since nothing is impossible and especially not in crypto) is something as extremely unlikely as Bitcoin hitting $1 million this year.
I don't get people who are in crypto and looking back at history still thinking it's the end, when everything else that's fundamentally guaranteeing its survival just keeps getting stronger.
