Hello, great question.  Mining is very simple via POS (Proof of Stake). You simply must have BTCA in your wallet of any amount and leave the wallet open and it will start staking after 60 blocks.   

On a technical aspect you need to first encrypto your wallet by choosing the lock symbol on the top right then set a password (which locks your wallet). Then press the lock again and unlock your wallet. Then you wait for the 60 blocks to occur and your wallet will start staking immediately whenever it is unlocked.

We will be listiing soon to an exchange where you can buy BTCA to start mining.    For masternodes 100 BTCA collateral is required. For staking in the wallet any amount will work. To put above 20+ might help changes more to win blocks.
