Everyone always says "don't buy at ATHs" but which one of the 10+ ATHs in the last 2 days am I not supposed to buy at?

$5800 to $6900. Been waiting for a drop or correction of more then $100 to buy.Is it safe to say now that the "don't buy at ATHs" is not good advice anymore? via /r/Bitcoin http://bit.ly/2z8MLV7
