This is a timely topic at the moment, because as the days go by, more and more fiat currency is being printed, which is basically causing inflation. This is why the value of our money is decreasing even after the interest we get on the money we keep in the bank. However, we also have to remember that it would not be right if we held all our funds in bitcoin, because bitcoin has volatility, which can hinder us from using the money all the time because then we can face losses.
Always have it at the back of your mind that the world economy is faced with inflammatory pressures on the regular, developments approaches which gives an edge to the economy growth same time costs of goods increases and while the central banks keep printing more monies, the fiats looses it values of purchase power. And worse comes to it if your government is more reliance on importation than exports, then is a doom to cause more recession outputs where the fiats suffers devaluations.
And that's why I think we should balance our assets between fiat currency, bitcoin, gold and as well as the land property so that we don't have too much of an impact from inflation.
Every market structure or economy system has it own pros and cons, bitcoin market is volatile and so also is the gold with their own potential to store values against inflations but best safe for diversification of assets and not a source on the regular extraction of income to sort your immediate needs. That's why we also need the cash in the bank so that we don't for emergency need obstruct our investment plans in the long term. Considering real estate is also a good one since it appreciates in values as much inflations appreciates too.
