Well, if this question was asked directly, then I will simply say, after holding and finally selling, the next thing to do  if possible is to life your life as simple as that, but unfortunately, most holders haven’t even thought about selling atleast not this very moment when they’re seriously seeking ways and money to continue buying.

All the other investment options you mentioned are relevant but I don’t think, a core bitcoin investor would want to  sell his coin simply to go invest in some  other things not even this bull run.
