There are ups and downs in the crypto market is a natural thing, even it can be a signal when it is the right time to enter or leave. One's experience while walking on the crypto market also affects one's success in making profits.
But still there are times that the price heavily increase (what we called bull run) then after couple of months pumping the market, it will goes down again. It could normally back to the price that it started to increase. I think were heading to the bear market, we just experiencing right now is due to several good news and events surrounds the cryptocurrency which is good thing. I agree ups and downs are natural to cryptocurrency, in that point we must try to sell when the price is high if we satisfied with it and then buy again if the price goes dip.
