anyone can help me with this idea i have a budget like 4000usd i want to invest it in trading crypto but in daily basis so i can earn as little as 0.1% from intial investment per day but with very little risk
Why don't you just staking your money? You can earn your passive income very nice from staking/farming your BUSD. this will give you guaranteed return for your BUSD. Your initial investment will be not at risk. What you need to do to go to the pancake swap and then try to farm use your money. You will get a chance to get passive income. As long as you're using stable coin for that and then you will not get disturbed by the volatility in the crypto.
Earning 0.1% from trading with your money was easy but i can suggest you to do farm or staking to get a good return. You will able to get passive income from there.
This is my 2 cents but the choice is yours.
