Of course it will drop again.
I would consider $1250 as a near certainty at some point in the next six months, even if this rally reaches all the way to $3000.
And as the poster above me mentioned, sell a portion. Sell even just 20% of what you plan on selling at $2000, then list another 50% of what you planned at $1998, then list some more at $2100, 2200, etc.
Never go all in, or all out.
