For earning from gold you will have to wait for years to get a few hundred dollars profit while with bitcoin you will get that amount in a few weeks or months.
If this is the case and profit is a guaranteed then why hasn't any major investor or hedge fund jumped into bitcoin?
If you think profits are guaranteed you need to take a second look.
From my point of view bitcoin has now stagnated, the most exciting thing for a long time (apart from all the exchange hacks) was halving and thats it.
No mass adoption, no new killer apps, no new big investors or innovation.
Moving forward I cant see anything that is going continually drive the price upwards apart from the usual pump and dump whale games.
