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
Trading is risky and there's no guarantee that per day you'll get to earn your goal of 0.1%.
Owning like $4k and staking it on interest accounts for a stable coin will earn you 8%-14% annually. Going with the example of 8% per year and that's 0.67% per month and you compute the daily.
For 14% that's 1.1% per month.
