Where to invest 7k usdt
To get profit daily 30$
all investments carry a very large risk. minimal risk in deposits to banks or to buy mutual funds or sovereign debt bonds. but obviously you can't get 30 dollars every day from only 7k dollars.
if there is please reply to my comment also want to join the investment also from the suggested.
Some of the lending protocols give a high APR for stablecoin investment. Even in centralized exchanges they are offering more than 7% APR which is not so normal. In manta one of the ethereum layer 2 protocol they are offering more than 15% apr for USDC deposits in some cases. There are numerous other ways to earn from this 7K USDT but these are the safest with a minimum risk investment strategy. You can use grid trading features in centralized exchange which can also generate more than 30$ if you pick a volatile asset to trade.
