Ah, I did buy some in 2014, 2015 and later...not buying now, apart from small sums...the numbers are not really important because I would not disclose despite your teasing and assumptions, but it is true that I am waiting until the sum reaches a certain high number, possibly, after which I would transition to phase 2. It's not going to be the distribution, but, rather, an organization of matters related to bitcoin and my extended family.

That said, it is possible that I wouldn't live to see phase 2 because bitcoin's price needs to be quite high for me to follow through.
Otherwise, I would just make a will or do a trust. Honestly, currently there is no good method of even giving bitcoin to someone because rules and laws regarding this are at a rudimentary level. You are not going to do it by writing a private code on a piece of paper and putting it in a safe at the bank or at the lawyer's office (lol!) and/or giving someone a trezor/ledger. They wouldn't know what to do with it...it takes quite intense learning to get it properly, as we all know.

I think that some people are paradoxically converting btc into btc etfs now because those units are VERY easy to inherit from you or for you to gift.
I wouldn't do it in principle because to me etfs are inferior to bitcoin itself, but I can see others going this route, especially when brokerages would be allowed to take your btc and give you etfs.
