I think bitcoin does not make people go crazy, depending on how they use bitcoin.
If people say that bitcoin makes people lazy to work, it's wrong. Bitcoin can even be a light work that can give you a big income. Although you can earn money easily from bitcoin, does not mean you have to lazy to do other activities. It takes wise thought to be able to use bitcoin well.
In fact, people who invest and use Bitcoin do not become lazy. Before, I am a person lazy, and I spent over 10 hours a day playing online games. But since I've invested in Bitcoin, I became more hardworking because I wanted to learn about Bitcoin and blockchain technology.
