Yup, that it, but I don't like it, I want to see more tokens :-) .I think I will use Jupiter Lend to borrow USDC and buy SOL when I think SOL is at a low point and likely to move up. I can deposit the SOL and earn APR while I wait, and then when it rises , sell the SOL to repay the USDC and see if I can have some SOL left over. I need to look about and see if I can get an apy on the SOL that is higher than the apy I pay to borrow the USDC
If you swap SOL for something like MSOL, BSOL, JupSOL, etc, you can get an APR around 7-8%. And if you want you can use it (at least JupSOL) with the multiply feature to get an APR even higher!
