Sumokoin currently ranked ~491th in market cap and ~5200 satoshi. The coin maximum amount will be 88.8million and includes 8 million that were premined. The coin is a fork of monero with a few modifications. Similar to monero the coin is mined using the cryptonight algorithm and has ring confidential transactions. The coin is focused on privacy, anonymous, and fungible. Fungilble means all sumokoins are equal in value, similar to monero.
Whattomine has the coin ranked near the top most profitable when mined. Coin was introduced around middle of 2017 so is very much new. The creators have their own dedicated gui wallet which is easy to use and have a 26 key words seed versus the 25 for monero. Just past few days the creators have introduced sub-address to further enhance privacy.
If I had a gpu to use for mining I would likely look into this coin. At current estimates there are ~2.2million mined so one can likely earn a very good amount if they start mining the coin now. I see the coin on whattomine up in top 10 almost everyday which in my opinion will likely to continue to grow in value.
