From an investment point of view, bitcoin is more about gold than it is about other currencies. That's because as an asset, bitcoin and gold have a lot in common. Both are limited to supply, both have functions to use, and many believe that, despite their large price fluctuations, they remain a good store of value. Compared to gold and currency investment returns in the past five years, the currency's performance is far better than the so-called precious metals, gold year loss than 6%, the currency of the annualized rate of return is 155%. These rich returns show that bitcoin has excited investors about the prospect of putting money into such a new asset class.
Compared with the gold standard, the value of the currency rising and proven performance, investors can be used to measure the investment of the world's leading digital currency future opportunity and risk indicators.
The limited supply of gold in natural but in case of bitcoins it is man made. I think they may even change this in future depending on the demand.
Now coming back to which is better in between gold and bitcoin, both have got their own advantages and disadvantages. One of the biggest advantages of bitcoins over gold in my opinion is that it is so easy to carry. Even the safety is not a concern. But regarding gold, it is very common to hear incidents of gold being robbed from houses or even jewelry shops.
