All I know is that a handful of science gets bitcoin.
#Bitcoin Mining
#Free Bitcoin Faucet
#PTC or PTR sites
#BitcoinTalk Signature Campaign
#Write news sites
#Bitcoin Trade
#Gambling
#Bitcoin Affiliate Marketing
#Bitcoin Mining - not really profitable today unless you have a huge budget to invest in mining
#Free Bitcoin Faucet - absolutely not worth it. Collecting change on the street will warn you more
#PTC or PTR sites - pretty much same as faucets
#BitcoinTalk Signature Campaign - Can be profitable but sometimes requires a higher rank that can take time to get
#Write news sites - if you have experience or know how to write articles then go on, it can bring in some good profit
#Bitcoin Trade - This requires some knowledge of the market also would recommend only to the experienced ones
#Gambling - Requires knowledge and luck, but will mostly lose you all in the end
#Bitcoin Affiliate Marketing - would be great if you own a blog or a website with a little bit of traffic
