It is better if our income is only enough to meet our living needs, don't force it to invest. We can participate in airdrops and bunty cmpaign to get additional income that we can use for investment.
I also have a business in the real world, but for investment I use income and profits from the crypto world, because I will not bring real world income to invest in crypto.
We only invest when we have excessive money. If we only have enough money for daily necessities, it is better to use the money for the basic necessities firstly. Sure, we can try to get the money for investment through bounty or airdrop programs. There are many of them in the forum, so we can try our luck. However, we don't choose random bounty/airdrops. We need to do analysis, choose the most convincing one only.
Anyway, having a job in real life is a must. We don't rely on the job in the forum only, or the job from crypto only. Sure, the income from the job in real life, should be better to use for basic necessities.
