Have you looked into the Liquity Protocol (https://medium.com/liquity/how-liquity-replaces-floating-interest-rates-a3e6ad16ece0)?

The idea is to buy ETH while it's low, borrow against your ETH at zero interest, and use LUSD for stablecoin farming as you are suggesting in this article. If ETH goes up, you get both the benefit of asset appreciation and stablecoin farming. If ETH goes down, at least you can still reap the benefits of stablecoin farming.

Another strategy would be to buy BNB and borrow against your BNB. RockStable will be doing a market experiment with a CPI-adjusted stablecoin in BSC, using a slightly modified version of Liquity (https://medium.com/zero-interest/stablecoins-and-fiat-inflation-a-commentary-558dc2ad2416).
