Few ideas for you to improve things.

1 Get telegram, discord, slack, roket chat, for support and community.

2 Incorprate new miner for new algo Signatum https://bitcointalk.org/index.php?topic=2030529.0

4 Provide more support for withdraw coins that are avaible to mine.

5 Detaild report for daily weekly, monthly and year report of coins mined when how much was generated and brake down of fee of coin.

6 Have option to to convert % of minted coins directly to btc etc or paypal or whatever payment options you have. So you can split say mining on eth at time % stays eth % gets converted to btc.

Just my 2satoshis of ideas for improvments. More to come when I think of some.
