My cousin with the phone number $ETH opened a short position on Ethereum last night and has made 100 USDT. She insists on treating me to hot pot. I said it's not necessary, and I still advise her not to trade contracts because I've suffered losses from contracts before. But no matter how I say it, she just won't listen. I'm doing this for her own good, but she doesn't know. Do you think I'm wrong?
