If you haven't already sold your ALTs simply hold if your project is decent. If the project has no future sell and buy into a decent project. This is all you can do to recover your loss without putting in more money. It will probably take a couple of years to recover your loss!
Some ALTs will never recover from this crash!
It is an ugly situation!
Those altcoins that can't able to recover are the shitcoins and We all know that. We can hold the coins if it is really has a potential and have a reason to to hold and buy it because it has a bright future ahead. But at the situation We have it now Holding is the best option for it to apply here in this business industry.
I agree, my portfolio consists of a set of coins, in which I invested 2017 and earned in 2018, but trading them is not profitable at all, the cost incurs heavy losses, it makes no sense to sell now, and perhaps over time any coin will generate income, and it will be great if it pays for all the previous investments and work done.
