I am completely new to this site. I have recently started learning about cryptocurrency. There are still many things I don’t know, you can say I only know a little. In these few days I have seen that people are very curious about Bitcoin. Everyone wants to know about it.

As far as I have learned, it is not controlled by any government or person. It is a decentralized coin. People call it digital gold. It allows people to directly transact with each other.

Now I have some questions which I cannot fully understand:

- Why is Bitcoin called digital gold?

- Does Bitcoin automatically go up and down or is it managed
  by any company or person?

- If I buy Bitcoin, will it be more profitable to hold it for a long
  time or for a short time?

- As a beginner, what should I do here? Should I slowly start
  learning from here or should I try to invest along with learning?


I hope the seniors here will try to help me.
Thank you.
