It depends on the cryptocurrency you have invested in. There are times wherein the market prices are low but not all cryptos would be able to go along with the price increase when such thing happen, only those who are 'strong' enough would get through so you better choose the best crypto in order to make profit from buying low selling at high peaks. Also, since the recovery times cannot be predicted, there will be instances wherein profit would be dull, but patience is the only answer with regards to this.
This time has been one hell of a time, predictions seem not to work,or sometimes one fundamental analysis will just disrupt the way technical analysis has been plotted, this period has indeed been full with instability, I think this isn't the time for trading especially as it concerns newbies. Just look for a good point,buy your coins and hold and then wait for moon.
This is the reason why holding is more advisable than investing at this moment. No one knows when will the market increase and no one knows what coins would be profitable to invest when that period come to existence. But investing is not a bad thing still. If you are that eager to take the risk and proper someday, you better choose the best investment at this moment. I would say Bitcoin is pretty a good shot to try, its price is still low, giving opportunity to investors.
