I've recently gotten a graphic card for mining but i heard that currently mining is not worth it as all cryptos are currently in the downfall so its not worth mining. Can anybody give me an advice on it. Your insight is very much appreciated. 
Why would you stop mining because the market is down, on the contrary, this is the right time for you to mine any coins you think has potential against when the market will recover, right now, many alts miners probably are thinking the same as you, remember that both bear and bull season are not permanent.
It is the same thing as buying a reputable project during the bear period because the price is very low due to the bear period. There is a saying that it is in bear market you build a healthy portfolio, this can also applies to mining.
It depends on a lot of factors, it's not as simple as you say, we are just holders, in addition to holding, we don't have to pay any other costs but mining will cost a lot and especially if OP lives in a country with high energy costs plus such a situation where many coins drop in price will easily lead to losses then mining can stop a time. That's why when the bear season comes, a lot of miners have to liquidate their excavators as well as their graphics cards, requires careful calculation to mine, it is not as simple as holding.
