When it comes down to APR, it mostly depends on the price of the token, if tomorrow that doubles in price the APY will go down by 50%. The whale selling is also one of the main reasons why the APR has been so high recently. So basically at this point, either the price of the token will go up or the dividends will go down. I made a chart of the 10-week average APY/APR (I never understood the differece) which shows it generally ranging between 38% and 60%. The covid perdiod when all sports were canceled early in the chart is the reason for the initial low numbers

As for as the smaller shitcoins go, I just let them accumulate in my account. It's nice to have a little bit exposure to them and if there ever is a time when I do need some funds it's easy to send them to binance and sell. They do add up over time and you also always can use them to take a gamble.
