Where to invest 7k usdt
To get profit daily 30$
maybe you should try staking, whether it's on eth or another coin, maybe you can earn 30$ per day or more or buy shares to get dividends every month, that's my advice, you should do your own research so you don't experience losses in investing.
Keeping his $7000 in Ethereum and staking nothing else can earn him $30 per day. If he can trade then maybe he can get profit for a few days but unfortunately if his 7000 dollars is stuck by trading then he won't be able to earn 30 dollars per day later. Here OP mentions how he can earn $30 per day from his $7000. If I could give advice my advice would be to invest $7000 in Bitcoin or Ethereum. If OP invests $7000 in Bitcoin or Eth then on average he can earn more than $30 per day when new ATH is created in the market.
