Those who accumulated coins at $3,000 per coin would be looking to book their profits very soon, and this is going to happen once the prices stabilize. Now it is difficult to predict for how long the current rally is going to last, but my guess is that it may begin losing its momentum after 10K. So we can expect a major correction to follow that level.
Those who accumulated that low might sell but the volume now is enough to buy their dumps.
So no worry at the moment, let them dump as it would not affect the market.
