I don't think it will just simply go up forever, but I think there's a hell of a lot more room to grow. The total market cap of crypto is still really low, even 10x growth would be kind of minor overall compared to the global GDP. It'll likely fluctuate similarly over time, but I think the time that BTC is below 10k is slowly coming to an end this year. So instead of it bobbing between 8000-5800, it'll probably be between ~16500-13500 or so. We'll see, nothing lasts forever though.
