Thank you so much guys. So, if I but an ASIC litecoinpool.org would do the trick for DOGE? I haven't found any info about how to swap from LTC to DOGE.
Yes but it needs to be a Scrypt ASIC and not Sha256 ASIC which is for Bitcoin. So needs to be an Antminer L3 or similar. Make sure the algo is for Scrypt. You merge mine with LTC so basically you get paid both in LTC and DOGE at the same time. You don't need to swap LTC to Doge. The way it works is if the hash you found is a block for both chains you get rewarded for both.
Keep in mind if you buy an old Scrypt ASIC it might consume more electricity than it gives in revenue, so make sure you do your research and use a mining calculator at least and put in your power costs.
Since you got a GPU, just mine ETH and sell ETH for Doge.
