Forex deal with currencies and so are exchanges in crypto market. Bitcoin is considered currency just like USD. There is not much difference to Forex and cryptocurrency market. We can also store our wealth in bitcoin which is exactly what you also mean with GOLD. Bitcoin is even better than gold because it can easily be bought unlike gold that you have to transact differently.
Actually, I have a lot of belief in bitcoin, so we have the opportunity to increase our sales. It's more valuable than the hidden gold inside. It's a strong, robust force that has many uses for people and the investor community to use,
i think forex is more realistic, because whales can't do much like in bitcoin, besides that i think forex is clearer news that will happen, we can see that schedule in forex factory, while bitcoin is pure from buying and selling.
