...Now if btc price drops to $700 some people will try panic selling and others enthusiastic buying and not only it helps to stabilise btc but it involves some btc circulation, makes it alive which is always good for money.
On the other hand, we can also see some traders will risk more by continuing holding their coins since they already on the verge of the loss. So rather minimizing the loss, they will face more risk. By doing that kind of risk activity, they must also take advantage of the said price decrease and go again for another round of buys.
Possible scenarios:
Bought @ $750 = Price now decrease to $680 = Decided to hold since already a loss and just sleep those coins waiting for price increase
Bought @ $680 = Price now increase to $750 = Up to the trader if it will be sold
Then the coins bought @ $750 will now begin it's process of waiting their desire price to sold it.
