I think that bitcoin is not new gold, more exactly bitcoin is a new type of investment that can give bigger profit than gold. bitcoin and gold are different because the bitcoin is intangible and gold is a kind of precious metal
in terms of bitcoin being intangible and gold as tangible is kinda obvious - what I think should we compare them with is their value. During the old good days of gold rush, the scenario seems the same, many people flock to mine and accumulate bitcoins just like before where people were also mining and trying to get golds as much as they could.
That a great compare - at first everyone is willing to gain more than others. But with Gold you'll never know how much there are out there ( because who found do not tell you) - with BYC will know since the beginning how much will be in circulation.
And beside gold, Bitcoin can really solve an issue here: getting rid of the banks that have been collapsing the entire economy.
Maybe Gold was used in a such way thousands of years ago when there was no other way to exchange goods. But now we live in a digitale and intere era with still a currency printed!
