I'm looking for a coin that has huge up potential and gains in the future like Ethereum haha but is mineable now obviously.
Monero. To me XMR is one of the most undervalued cryptos in the market and has huge potential to be 'like ethereum' in the future. The rx580 is actually really nice mining XMR, I think you can get around 850 H/s or 890 H/s (OC) each, so if you have 8 of those you're looking at almost 9k H/s.
