That's the irony of managing a portfolio mainly constituted with altcoins. Actively managing such portfolio is extremely difficult because of the uncertainty of this nascent market. In this case, most people would make more money by passively managing their portfolio due to volatility. However, we're not sure if there's going to be a future for most of these projects.
The best strategy would be to reduce your risk exposure by avoiding the markets for now unless you have the expertise to strive with the ups and downs. Personally, I would wait until all government regulations are announced before investing more.
