- Why is Bitcoin called digital gold?
Firstly, let's find answer from the resource where you got the term Digital gold and I believe you can find available answers and explanations there.
Secondly, in my opinion, let's call Bitcoin as Bitcoin, nothing more, nothing less, and surely I dislike to call it as Digital gold.
- Does Bitcoin automatically go up and down or is it managed
by any company or person?
It's not automatically go up or down especially upward movement in long term. Bitcoin must have good value in order to be accepted and wanted by many people so that they create buying demand on the market, and lift Bitcoin price up over time.
If a cryptocurrency can go up automatically, you would see the same with altcoins while the reality is different - most altcoins die over time.
- If I buy Bitcoin, will it be more profitable to hold it for a long
time or for a short time?
Invest and hold your bitcoin in long term as history shows that if you can hold bitcoin for years, more than 5 years, you would have gotten profit.
