No it is no need to say no to bitcoin in any situation, as if it is time to dump in price then it is important to hold your bitcoin, most of time people buy bitcoin at time of dump price, red market means price is going to be low but at the time of green in market you can sell to have profit, no body want lose because price get high once again when it get down, we will have to wait for price of bitcoin to be high, take the benefit of bitcoin volatility no need to sell it, hold it and be patient.
