Hi still a newbie trader here. Just want to know. If All altcoins are down since last few weeks. How do traders maker their earnings during this bitcoin correction / retracement. All my polo coins are bought while Bitcoin is 2900usd in the past few months. Now I am HODLing like forever

All my coins are in bloody red, I have negative -20% to -30% profit. Please suggest something.
There are several ways, one is to buy even more bitcoins, this may seem insane but follow me, if you bought 1BTC at 2900 then you need bitcoin to higher than that to get earnings, but if you buy another bitcoin for 2285, the current price, now the average price of each bitcoin goes to 2592.5 so next time the price rises you do not need the price to go as high as before you only need bitcoin to go above 2592.5.
