When we are in an inflationary situation that causes the economy to be tough and the average price of goods is rising, investing in Bitcoin is the thing to do to maintain the hedge for years.
There is two problems with this which is why price isn't yet rising.
Many people still don't know about bitcoin or still believe the FUD they've been fed over the years so they stay away from the only reliable hedge against inflation.
The other problem is that people invest their money if they face small inflation but in most countries like in Europe we have much bigger than normal inflation and even hyperinflation. Not to mention that in many cases inflation is mixed with recession like in US which means people don't have enough money for their regular expenses let alone have anything left for investment.
