Bitcoin SV is a hard fork for bitcoin cash, so we need to first understand a hard fork.
What is a hard fork?
A strong fork is that when a single currency is divided into two simple terms in simple terms, if you own a single currency before, you will own the same amount in both cases.
Profit
In this case you can gain about 40-60% from the fork. Because if you own 1 Bitcoin Cash ($ 200), then after a fork you own 1 Bitcoin Cash ($ 200) and 1 Bitcoin SV ($ 100). It was calculated at the end of 2018 prices.
So from this point on, you have either chosen to keep, both can sell or simply have features / teams like your choice and one of the other things you find as the best choice for investment and currency.
