Actually more reason that you should not either push the red button or employ option 3.

Hey, mindrust, I think that you already know that I don't give two shits about what you do, but since we are posting on a public thread, of course, if you are bringing up ideas regarding investing and overinvesting and all of that, many of the responses are meant for public absorption... or at least consideration of the ideas.

Accordingly, we know that it is different to invest 25% and/or to achieve 25% based on BTC appreciation.

These surely are considerations that any investor into BTC should be making regarding both how much to invest and whether or not to reallocate.  Sometimes choosing NOT to reallocate is a kind of additional investment, especially if the Bitcoin value (proportion) of your investment becomes way the fuck beyond your initial allocation authorizations. 

Personally, I am NOT so much into needing to reallocate in an asset like bitcoin merely because it has blown other investments out of the water, but of course, opinions are going to vary on that topic, and none of them are really unreasonable - even though each of them can contribute to individually considering the extent to which you are either overinvested, underinvested or adequately covered in your various other investments.

I know that there are people who do not have a lot of kinds of investments like stocks, bonds, real estate, PMs and other investment vehicles, so these calculations are going to differ too, regarding how prepared any of us might be on an individual level if one or more of the investments went to zero.. and of course, if there is only one investment, then the risk becomes greater.. at least in the scaling of "overinvestment" calculations, ponderings and considerations.
