What influences my income and profit?

SHA-256 is used to mine Bitcoins (BTC). This means, that the only factor which influences the income is the mining difficulty. You can see the difficulty growth chart here - link.

Scrypt is used to mine Litecoins (LTC). This means, that there are 2 factors which influence the income:

  1. the difficulty of mining (chart - link);
  2. the exchange value of LTC/BTC (chart - link).

Scrypt payouts are converted from LTC to BTC and then added to user's balance. 

SHA-256 and Scrypt contracts are also subject to daily maintenance+electricity fees (MEF) which are deducted from each payout. Currently the MEF is 0.0035 USD per 10 GH/s of SHA-256 and 0.005 USD per 1 MH/s of Scrypt.

Once the MEF is deducted from a payout, the remaining amount is considered your profit.

*BTC/USD exchange value also influences the MEF (chart - link).

ETHASH is used to mine Ethereum. As the payouts are provided in ETH, the only factor of influence is the difficulty of mining (chart - link). 

X11 is used for mining DASH. The main factor influencing the income is the mining difficulty (chart - link). 

ETHASH and X11 contracts are not subject to any additional fees.
