How much risk are you taking on?

I'll go first. Mid 40's. Wife/kids. $4M portfolio excluding residence. No debt. I'm at 4.5% Bitcoin. I'd like to get to a certain round number of Bitcoin but that would pull me up to over 7%. I'm not certain that's responsible given my life situation. If I was younger had had less responsibility and less to lose I'd probably be shooting for 15-20%. Anyone here going crazy with their risk despite family/life responsibilities?
