It's been over 2 months since I updated progress on my mining...
Currently I'm using 1 Android phone, 1 Android tablet, 1 laptop and 2 PCs to mine Alloy Cash and B2B Coin.
Alloy Cash is good coin to mine on Android devices as the pool I use (alloypool.com) has small minimum payout threshold (0.200 XAO) and supports miners with very low hashrate (a.k.a. toasters). NeoNeonMiner on Android gives about 5 hashes/second in total for the two Android devices. It takes about 36-60 hours to get 0.200 XAO at 5 hashes/second (difficulty about 100 million).
The laptop and two PCs mine B2B Coin... It has pretty decent network difficulty between about 10-25 million and minimum payment threshold on the pool I use is 0.010 B2B so usable for low-end computers.
Both Alloy Cash and B2B Coin have GUI wallets that support fusion transactions which is essential when using mining pools with low minimum payment threshold.
