To save money on a long-term period, you should make a solid investment. Investment in crypto has a lot of potential. Even during a bearish trend, don't hurry to sell crypto. This is just the phase of corrections which is perfect for holding. Invest now and get profits when the market finally stabilizes.
The primary way to save money that is suggested by the policy makers and the economists is to reduce the consumption. Minimize the imports that cost you more than you actually can afford. Such imports hinder your ability to save more in the long term. Besides, the more you produce, the more you would be able to earn and hence save.
There are lots of ways you can actually get your current account surplus. Long term investment in potential coins in the crypto market is the second name of getting your money replicated and the growth is often more that what is normally been paid in the bank.
To me I think that the best way to save your money for long term is to invest it in bitcoin or in some other low priced crypto currency where you think that in future their price will increase too much. I hope that through this way you can not only save your money but can also get a good profit from there.
