Bitcoin is simply better because it is decentralized. Because no matter when you invest in it, in time you will become richer
In an investment point-of-view, yes. For monetary point-of-view, yes, as gold is bulky and is harder to transport. But then again, neither of this things are the main uses for gold. For one, store of value is its primary use-case, IMO. Second is being a standard of value: no matter what era you are in and wherever you are, gold will always be considered as money, and can therefore be replaced for goods and/or whatnot. Both (bitcoin and gold) has its pros and cons, and I'm pretty sure we have been through this time and time again.
And gold can be tampered with, unlike Bitcoin where the blockchain takes care of that automatically.
For gold, you need to inspect it. Even ingots have been known to be faked, taking out some of the gold inside. You could recreate gold coins, but counterfeiting will thrive, and not everyone has the capacity to detect the fakes. Like the ingots, all it takes is some metal that weights about the same and cover that with actual gold.
The Roman Empire actually started their inflation by literally reducing the amount of gold used in their coins, until there was no gold in them anymore
See how gold is not so convenient anymore? Can you ever certify the gold reserves are 100% gold? Almost no one is allowed in, you have to trust the word of a select few. Going back to backing fiat with gold is simply lying to yourselves. Besides they also practice fractional reserve, you can bankrupt a central bank.
