All one the internet people are getting scammed daily. And bitcoin does revolve a bit around these problems. How? Bitcoin is revolutionary, but is also very good for scammers. You see, people that scam will say you can get free bitcoins from mining. Which is true, but when using their full proof system, you can 'earn' thousands UPON thousands of bitcoins. That's false. One reason is because when mining bitcoins, the network that creates bitcoins only releases about 25 BTC every 10 or 20 minutes. So making thousands upon thousands is just impossible. The bitcoin network also estimated that they would make ~21 million bitcoins before stopping. The usual process would be not a .com domain, you must complete a "survey" which requires a credit card and doesn't even work *sometimes. Also, if you can download it without a survey and earn bitcoins, make sure it's legit. The only legit bitcoin miners are for example CPU miner. Or GPU. where you must connect to a pool/server, and must wait a while for the computer to complete the process.
