I think both of this is a good investment. If we hold gold and bitcoin we can earn a good profit, and they have a future. Because gold is its prices is increases and it has maintain its value. While bitcoin has a future and earn good profit. Both of this is a good investment and the price may increase. Both are a value and each have an advantages and benefits and they have a future. Both are a profitable and safe to hold. Both is for our savings and this very exciting investment opportunity. And bitcoin is most popular than gold to people and to investors.
i think gold is not an old concept, people interest is now decreasing there, because there are very little chance to get profit from gold because we can expect a very small chance in the price of gold, therefore i think now people want to invest money in bitcoin, from where they have more chance to make more money depending their investment, experience and knowledge.
