Obviously with a 130% increase in the bitcoin price over the last year the peel value now is much higher, just as the auction value is as well where I'm guaranteed the current spot price plus half of the buyer's premium, but what matters is that I used a good portion of the proceeds to buy the Blackrock's iShares BTC ETF https://finance.yahoo.com/quote/IBIT/ which is up by about the same amount, and my prime motive was to preserve those coins, and to get them listed in nice catalogues for posterity where I can still enjoy them, but without the needs and risks of physically holding such a large stash, plus to help to kick start the nascent main stream physicals crypto auctions market, Heritage reported to me this about my latest sale:

"As per the last sale we’ve just had on Monday, it was definitely our smoothest and most profitable crypto sale we’ve ever had, so I consider it a great success."

I had other uses for the proceeds as well last year which were more important to me than maximising the amount that I, or my estate, may get at some point in the future, I've waited well over a decade before selling and this is now an opportune time as far as I'm concerned.

I have taken on some costly philanthropic commitments which are making a huge difference to some people's lives and have being doing this for some time now, I've also diversified into many non crypto fields and after having all of my eggs in one basket for so long this gives me more security and some very nice places to live in around the world, this is the stuff that I enjoy spending my good fortune on now rather than trying to maximise my net worth beyond my needs.

You've stated that you don't care for auction house sales and that is your prerogative and choice, but it isn't mine obviously and I have no regrets about my auction sales to date.
