The PoW (mining) period on this coin is long over. 

There are three current ways to earn 8bit:

• Run a masternode (initial investment is 112 8bit)
• PoS (proof of stake,  it's kind of like an interest rate on a bank account)
• Lastly, there is a faucet 8bit.netspecto.com which will get you some free 8bit, but at fairly standard faucet speeds,  but it's free!

For a fairly small investment the first two to generate a more-than-decent return. Much more than mining most other coins unless you're investing seriously in mining gear.
