I was born in 1993 and at that time the price of gold was 100 times less than the current price. The price of vegetables and fruits were 30 times less than the current prices and the fact is the prices in developed nations is still not increased in their that much but in poor countries it did.. why? the reason is all around the economy. My country is suffering because we are indebted by IMF, the printing of excessive fiat and off course the corrupt mafia politicians who are their to serve our country instead they are parasites and feed on our bloods. So, your suggestion of buying bitcoin an holding it for long-term could give even a middle man a bountiful output.
Gold is a precious metal or a type of an asset which appreciates in value overtime. So its value have risen by many folds are not caused by the inflations. Prices in developed nations did increased too a lot mate. There is even that picture I saw last time on how the items in the US got heavily affected by it.
And then, there is also that picture of a dollar that it's like it is burnt or teared down on some of its parts, showing how its value got degraded all throughout the years. But after all, they still have an edge over us like the value of their money is still higher than on us but that is also a good thing if we are paid in other currencies like the dollar, because it makes our salary to get pumped up a little.
