the alistair milne tweet.. doesnt make sense
he explains
'DCG has ~$2b of debt.. so needs high fees to use high fees to pay off debt'
'DCG has ~$2b of debt.. so needs to sell $2b of its locked coin to pay off debt'
all in the same tweet..
however even at a discount lets say $40k/btc
selling just 50,000btc would cover $2b
however grayscale dropped by over 100k and still dropping. (502k from over 640k = over 138k)
or in fiat terms they took $5.5b+ out of their own game
its not a high fee to use fees to pay debt. its a high fee to create a closed door to not introduce new share buckets to compete with the need for grayscale to sell its own shares and then relinquish control of those coins
You are not really pointing out any place that is contradictory and/or confusing, except maybe you are making it confusing in your own way of clarifying and confusing at the same time (a unique franky1 talent... hahahahha).
1) I think that any business should have goals to maximize their profits, and surely if they have gotten themselves into somewhat of a financial pickle, then they could engage in a variety of tactics that involve both selling some of their own GBTC shares, but also keeping the fees up on everyone still brings in way more fees (even with a so far bleed off of 21.5% of their funds - if we use your numbers).
2) I am not clear exactly how many shares of the 138k BTC would have had been Grayscale's, and maybe it is not even close to 50k BTC that they have sold, but others are selling their own GBTC shares and so then Grayscale has to sell the underlying bitcoin when such sales happen from their various clients.
I am pretty sure that there were already estimates that GBTC would end up losing around 25% of its holdings in a fairly short period of time once the competitive products were offered, so it is almost as if we are in the ballpark of that earlier estimate, and maybe it ends up getting up to 30% to 40% of the total AUM lost, in the next 3-4 months, that is still not going to be any kind of major catastrophe for Grayscale, and they likely are still doing better by keeping their fees at 1.5% for the whole year, or maybe they will reduce them at some point later down the road, but they may well still be better off to do a more gradual reduction in their fees rather than engaging in the race to the bottom that the newbie entrants seemed to have had tried to inspire, in which Grayscale likely does not need to play that game, even though they are getting a lot of negative press in the last 2-3 weeks.
