I'm going to bump this because Unobtanium has seen a significant dip in difficulty.
Now is GREAT time to merge mine UNO. You have a great opportunity to find Uno blocks. UNO mining is VERY PROFITABLE right now, according to Coinwarz.
Unobtanium is now listed on major exchanges such as LaToken and Bitcoin.com, as well as many other exchanges.
If you're looking to diversify your SHA mining revenue during these times of low BTC block rewards and high competition, or if you just need a way to lower your Bitcoin pool's expenses, consider adding Unobtanium auxpow.
UNO was fair launched (no premine) in 2013. It is in its low inflation phase (<1% annually). Active community
