The selling of such high amount of coins will definitely be felt by the market for some period of time, maybe a few weeks or so, but it won't stop the bullish market, because it's only 1/750th of the entire supply, it's clearly not enough to objectively crash the market. The US government was selling seized coins in the past too and it never had any serious long-term effect on the price. So now is a good chance to accumulate a bit more coins if you still waiting to do so, because there's definitely going to be new ATHs in this year and maybe the next year too.
