What are the best free applications for earning bitcoins easily and safely ?
There is a cool app called
Spark Profit that allows you to trade BTC and other currencies, commodities, stock indexes, etc. for weekly cash/bitcoin prizes. It is free to play on browser or phone. It's not a lot of profit but it is decent. It's not that time consuming if you just put in a good trade and let it sit.
The best part about this app is that once you sign up, they give you 70,000 points to start with and allow you to post whether a commodity, price index, etc. will go up or down.... Once the week starts you can place a bet wherever and say if you choose that it will drastically go up, you can set it and literally never check it again until friday or whenever the market closes. It's an easy way to make some bitcoin if you have a knack of knowing what's going to happen in the markets.
