Hello and welcome.
None if you only have one GPU, especially if it's an old one such as the 970. I don't recommend mining until you have well over 100k invested into crypto. And even then, mining is only worth a though if you pay 3-5 cents per KWH. Otherwise don't bother, since you won't be able to compete with the industrial scale mining farms (they drive the price down to the break even point).
