Why isnt it also a commodity like oil? it is the fuel for its blockchain. You cant use that public resource without it. It is built to plunge and surge just like oil prices do, based on supply and demand, which also comes in seasons just like oil.
Most commodities have seasonal patterns. Bitcoin trades like those.
It isnt controversial when a conmodity plunges and surges. Its actually better for different parts of the population at different times.
