Now my bitcoin cash has lost its value to 8.73$

but I'm going to make a few bucks more using that method I earned these so far.
If your earnings are continues then I suggest that you convert it to stablecoins like USDT if you don't want to lose its value but if you would like to take the risk then it is better to convert your Bitcoin Cash (BCH) to Bitcoin (BTC) since Bitcoin has more potential to increase its price compare to Bitcoin Cash.
