I trust Bitcoin in a sense that I trust that it's a secure decentralized psedonymous currency that can be stored and used without intermediaries.
As for the price, I expect Bitcoin to have more bull and bear marker in the future and expect it to recover from every bear market, even though I realize there's no guarantee that it will keep happening.
I didn't invest at $60k, and I think doing that would be somewhat unwise, but I do think that even those who bought at $60k will enjoy profits from their investments in the long run.
The price of Bitcoin can go below $20k, but I think it's unlikely to happen.
