I like bitcoin because it's decentralize, anonymous ( can transfer without add any personal data ), and easy to earn and spend.
I like bitcoin because you can use it different kind of transaction without any paperworks or hassle. Using bitcoin is nice and you can earn bitcoin in easily and instantly. You can also use bitcoin in your business like in investing or in trading.
Currently the price more than $2500, and I see not easy to earn bitcoin, need hard and smart work, if we mining the difficult level also increase but the maintenance service increase. I think the best way to earn money is buy bitcoin and then waiting until the price go up.
