Rotated $600k from alts to bitcoin last month. Sell now or hold and forget?

Back in August, I had about $130k spread across a couple alt positions. I managed to time one exit better than usual and decided to roll everything into BTC about two weeks ago. Honestly, I got lucky, no way around it.

Now the position’s sitting around $600k, and I’m trying to figure out the next logical step. I’ve been through enough cycles to know how quickly things can reverse, but it also feels like Bitcoin could still have room to run if momentum holds.

I don’t need to cash out immediately, but part of me feels like it’s smart to secure a portion instead of just riding it blindly. On the other hand, every time I’ve sold too early in the past, I ended up regretting it.

For those who’ve been here before, how do you approach situations like this? Do you scale out gradually, set targets, or just stay long and tune out the noise? I’m trying to stay disciplined this time, not emotional.
