This is what should be done, that we should invest using money that is specifically for investment, not using money for other needs, especially if it is borrowed money.
I even suggest, when we invest we should also have an emergency fund that can be used in a very sudden time. So we will not interfere with our investment at all because we still have an emergency fund.
I agree with you, in investing we should use free money and we should also have emergency funds. If suddenly there is a sudden need, it will not interfere with our investment.
We also should not use borrowed money to invest in crypto, this is very risky.
because the crypto market is difficult to predict and sometimes we also make mistakes in making analysis.
In general, investment is indeed profitable, especially if we invest in bitcoin. However, there are points that we must pay attention to here, one of which is that the market is not always in a good situation, sometimes we experience unfriendly market conditions.
Therefore, preparations as I said earlier are very important to do, because it will affect our investment in the future.
