Both bitcoin and gold is a good investment, but gold is more stable and more suitable for a long term, while bitcoin is more suitable for short term, and real reason to hold bitcoin is to beat inflation, as we know if we invest our money in fiat then every year our investment value is going down but bitcoin wont be influence by inflation
There is absence of inflation when it comes to investing money in bitcoins and even the price of bitcoin keeps on appreciating over a period of time and that makes it really attractive investment and you can also get benefits from it in short term which is totally missing in gold.
Bitcoin is good for use both in the long run and in a short time. This is very profitable. At the moment, I have a desire to accumulate a lot of bitcoins in order to save them in the future. Gold does not interest me very much, it will not yield high profits
