To get profit daily 30$
I think that at the moment there is no investment that can give you $30k daily profit with $7k capital, because it is impossible, but if you are looking for an investment that can make your $7k increase to $30k, then I can suggest you to invest in ETH and BNB right now, because I believe that during a bull run, then the price of ETH and BNB will increase very high from the ATH price, so if you invest in ETH and BNB at this time, then there is a possibility for your capital to increase from $7k to $30k.
make profit consistently about $30 every day without losing? I don't think so, we could be earning $30 from future for a whole month and then lose all those profits in just 1 day.
thats the thing with trading in general, no one really knows how it might turns out, after all its very random.
if we could easily make such consistent profit, we'd be rich but things harder to do than said.
