We should be able to use the money we have earned for good things, we keep it on deposit or use it for investment so that when we are not working we still have money saved so we don't owe or sell assets.
We ourselves decide which method to use, the OP gave us two choices to use the money we have, but do we need to choose Investment or Deposito?
1. Investment
Often we listen to advice regarding the use of finance, in this case many people offer solutions for investing. Then the question is whether the investment can be profitable?
There are several investment methods that we can use in Cryptocurrency, Bitcoin or Altcoin, as far as I know Bitcoin can maintain value, so that the use of money is much more targeted, although we cannot ignore the fluctuations and risks that will arise, Bitcoin has given a lot of evidence to choose from, so there is no comparison with altcoins.
2. Deposits
Deposits are more likely to be interpreted as saving money in a bank, deposits generally have a period of time for the owner to be able to withdraw the money, because they are vulnerable to maturity given by the Bank, more simply deposits are products issued by banks, so there are many restrictions that must be met.
In a more general elaboration, deposits can actually shorten the use of the money we have, so that the achievement of profit targets is not comparable to investing in bitcoin, because the profits provided are not large, even though deposits are also investment instruments offered by the Bank.
And don't be tempted by offers to buy things we don't need such as gadgets, electronics, cars and so on.
Humans live full of prestige, so chasing something that is not needed, this way of life is not a good behavior, because it will make people buy things not because they are needed.
The three things you mentioned are other instruments and have different meanings. Sometimes people see these three things as something that is needed, but some others see it as a way of life. The class and degree of a person's life must be different, as well as the needs that must be met, but if life is brought to a simple nature, then the needs will definitely be adjusted and place something wiser.
