This is an interesting question. If you compare the Bitcoin chart to the GOOGL share price, they look totally different. Google looks more like a straight line and makes no sense on a log view.
On the other hand, the APPL chart does look like the Bitcoin chart - it has a few big booms and busts and looks a bit logarithmic. Why is that the case? I have no clue.
it actually isn't that much different.
when the investment is great, these things grow fast > enter a bubble > bubble bursts > correction > rise again.
these markets usually attract a certain number of investors. it is not like bitcoin from all around the world, each day fresh money coming in and be able to buy literary any amount.
so on a smaller scale i believe we can consider them the same.
what i would like to see is their orderbooks. i believe that can be a very good comparison with bitcoin markets and their orderbook size.
for example how much money does it take to buy these shares and cause a 5% rise. how much for -5% drop
