Didn't yet see the reason for the drop, but I will surely use it to grab better positions for myself.
It's just due to going sideways or due to any other reason, after all, market is very affected by the sentiment, currently.
Why some will be busy thinking and looking for the best reason to justify why Bitcoin price drops in price, accumulators will seize the opportunity and buy cheaper; seeing an opportunity to acquire something at a cheaper price is rare, so if you will take advantage of the market drop and buy instead of still waiting to see if it will drop more, it will be better for you, as it will be using a small amount to accumulate a high unit of Bitcoin.
