i don't know with other people, but i choose bitcoin is because bitcoin can help me to make real money that i can use to buy something and i can make little saving in my bank account.
Great of course that Bitcoin allows you to earn a few extra bucks, but through what ways do you earn these coins? Would be interesting to know instead of only saying "I can make money with Bitcoin".
Earning here is just part of the bonus for supporting bitcoin but it is not really the benefits, the big benefits here is that we were able to transact online very fast and cheap and we can consider what we are holding as our investment in the future.
For me, earning is the best reason why i choose bitcoin than other digital currencies. With bitcoin, i can earn money without spend my money. Other digital currencies like paypal and perfect money also have, but the rates is really low.
