My advice is - Don't do it.
It's not profitable currently and it's a big gamble to bet on some shitcoin mining right now, Ethereum moved to PoS and all forks are not doing good.
If you really want to invest in something your 7k-8k it is better to just buy Bitcoin and hold it in some cold wallet for few years.
There is no guarantees this will pay off in future, with currently crazy situation we have in world, but you can diversify with other assets like gold and silver.
