Bitcoin is the Gold of the new era. This is due to the fact that bitcoin is having more worth than Gold.
Bitcoin isn't worth more than Gold. It's pointless and completely irrelevant to compare Gold's troy ounce price with Bitcoin's whole unit price. Another point is that just because an asset has more value (which in this subject isn't the case at all) than the other, it doesn't automatically mean that it is better.
Gold cannot make you rich just by holding
In most cases this isn't even what people holding Gold are looking for...
but bitcoin can for sure make you rich just by having some in your account.
Define 'some'? In current times there is no such a thing as becoming rich anymore. Especially not when you consider that many people can't even afford 1 whole Bitcoin.
