if you managed to buy at $40700 then you managed to buy at an excellent opportunity and you would sell as soon as the price shows some reversal of falling back to $40700. if you want to buy below $40,700 then i think you must be someone who would be counting on luck in this scenario because in case the price goes up above $44000 it will start to recover and as we know this drop must be related to the fact that the price is not have managed to break the resistance that is at $52000 plus negative news from china so price recovery will not take long
in that case you bought in $40,000 you made a better choice
