I really think that Bitcoin has the potential to outclass gold as a global currency standard. The main reason is that gold is becoming way too expensive in terms of storage and shipping. Furthermore, if you plan to use gold in global transactions, you have to undergo burdensome customs procedures, that do not apply to Bitcoin or other cryptos.
If you truly have the knowledge of BTC and you know how to employ some tactics that will make you to earn good profit from BTC investment, you will prefer BTC over gold investment because there is no how you will hodl BTC for 4 years when you will not boost your profit.
Many people have seen many rewards that made them to change their minds to embrace BTC, you can hodl gold in 4 years and you will not earn suitable profits, but if you hodl BTC in those years, it will make you to know that BTC is more profitable than gold. Even in global transaction, people prefer to use BTC in their global businesses than gold because BTC network is reliable for long stance transaction.
