Bitcoin and Ethereum are two of the most popular digital coins today. In terms of value, bitcoin is much larger than ethereum, but in terms of potential, ethereum is quite capable of dealing with bitcoin. So you think which one is better?

I wonder whether Bitcoin has been hacked in the past?

I heard that we can make much money by mining Bitcoins before, but now we cant anymore. Why?

I have heard about Bitcoin from a colleaugue at my workplace. He told me about Bitcoin but I couldnt understand well so he sent me some articles to know more about it. Thanks to him, I get more knowledge about Bitcoin know.
