Very rarely are any of the SHA alts more profitable than BTC to mine.

Currently, UNO returns 27% of regular BTC mining. Not worth it, to say the least. And if you're going to mine any of the other flaky shit coins like SaffronCoin, mine and sell-off as fast as you can before the coin flatlines.
don't let you tell bogus.
Uno is a good choice as it's on the up and btc on the down. In Uno you have less competition from other miners and those coins will be worth much more in the future. Mine the coin that's on the up, not the coin that's on the down. If you want mine and sell directly mine bitcoin or flaky shitcoins. If you want to mine and hold - mine Uno. Uno is top notch altcoin and will likely appreciate a lot this year.
UNO is a fine coin... one of the best alt coins, in my opinion. But anyone with a SHA ASIC miner would be a fool to mine a coin that returns only 27% of what they'd earn mining BTC.
Yes; much better to sell the SHA miner for Uno directly, bypassing all the middlemen involved in the convoluted route from SHA miner to Uno coin that is fraught with fees and risk.
