Both types of investment need to be added in asset diversification mode to stabilize asset values if one asset experiences a loss, we can also add other assets including real estate, shares, land and others. Don't place on one asset as we are advised to have at least 2 different assets, however gold and BTC are the perfect combination for long term assets.
The situation of fiat is increasingly worrying due to the impact of global finance, the value of fiat is getting lower but the prices of goods and services are increasing greatly, so prepare yourself to choose assets that you think have the potential for future profits.
If we have several types of investments that we make, of course this will be very good for our future, because this will make it easier for us to meet our needs in the future and if we don't have investments for the future, of course this will be very makes things difficult for us and we have to try our best to be able to meet the needs needed in the future.
So it would be very good to save and use the income we have well so that we can invest for our future.
