The price would tank to near zero before even 1/3 of that stash is sold, considering all the existing buy orders.
That would deal a deadly blow to the market and recovery would be hard when people know that SN still has plenty of coins to dump
For some value of 'near zero', I could buy 1.1M BTC. And I would. As, I imagine, many others in this space would as well. Thereby leading to that figure of 'near zero' not particularly near zero.
