Normal thing especially if you've been with multiple altcoin tokens. Altcoins are known to generate bigger profit due to larger increase rate on their market prices, but same goes with its volatility with price decline. If you are with good altcoins then there's no need to worry that much because recovery will take place eventually. However, if you are just engaging with "hyped" tokens then you'll need to have large amount of patient to be able to wait for things to be in green marks. As long as there is a decent volume then there will always be a possibility for recovery that you should wait. There are also times cutting the loss would be an option but be sure to bare with the permanent loss on your portfolio.
No concrete answer but the altcoin crash may be actual till the end of the current year. Maybe, in a few months some corrections on charts are possible but for the long term, small altcoins don't have a survival rate, in my opinion. BTW, the volatility of the altcoin market makes it possible to melt the whole portfolio in a few weeks and the market can fix itself in a few hours. That is why it is called the crypto roller coaster, better to hold until green takes control back in every sphere of the crypto world. Just my 2 cents.
I actually see it the opposite; market price could increasewithin months and could be "melted" within a day or few. This is why it is a must to have stop loss and market behavior plan. If you give importance to the money you engaged, make sure to have it on your full time and not only when you're up.
