It depends on the coin you were hodling. Most of the time, new coins that was being listed were not increasing and the trend always go down. I hodled a lot of coins from bounty and I am monitoring their price. Majority of them depreciate and not the price is getting worst. Its better if I sold it when I receive while the price is high than hodling for more than 6 months only to know that the coin loses its value.
At least we can hold it first until the end of the year, because usually the price of coins is always at the top level. There we can conclude whether the coin that we hold will develop or not.
