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.
