Bitcoin would give quick returns than Golden? Yes. Then why didn't they invested earlier?
Bitcoin is quite speculative so there are many people who may still be very hesitant to buy it. But over time bitcoin has gained a much bigger place in terms of adoption so that now bitcoin is much more developed.
Bitcoin could soon become a legal tender?
For most countries I still doubt that bitcoin will become legal tender because every country has an official currency that is regulated in the law so to make bitcoin a legal tender will require a revision of the law that needs to be approved by parliament.
Gold won't be as profitable as Bitcoin immediately he is sworn in as president?
But gold is much more stable and most people still believe in gold as a much safer investment. I am not so sure after he is inaugurated gold will not be profitable because this has been going on for a long time and gold is still the best choice for most people.
