Gold is old time fashion. In this time it is also fashion but not like as a past. If you buy gold and then sell it gives you loss but if you buy Bitcoin and trade you can get bigg profit. Its reason people are investing in Cryptocurrency more then other businesses.
How can you say so that it's old fashioned? If it's old fashioned then it shouldn't be existing as a luxury jewelry right now and it shouldn't be used for that matter even during the times of war? The reason that you give regarding why people invest in cryptocurrency is pretty shallow to be honest, not everyone can invest in gold you know?
everyone I believe can invest in gold if they want. Gold is not as expensive as you think. most people do not invest in gold because the price movement is not that big. even suitable only for the long term.
while bitcoin you can use for the short term and long term. the crypto market can give you a quick profit or a long-term plan.
I'm sure it all depends on the choice. safe assets for the long term. or assets with high returns with great risks.
