What to mine with an Innosilicon A10 Pro+ 750MH/s asic?

Given the explosion in price of crypto lately, I’d thought about mining again with my Innosilicon A10 Pro+ 750MH/s miner just to “stack coins”… What should I mine (if anything) to stack up coins that will increase in value over time?

P.s. I can mine with the ETHASH or ETCHASH algorithm either one.

Thanks in advance!
