Binance just listed that token because they want the trading fees from users like your friend who are riding the DeFi hype. Not all projects in there are legit and if you want to check how it's performed after the hype - https://coinmarketcap.com/currencies/sushiswap/historical-data/
If you're going to buy now, you're only giving your money to the people who are waiting to dump and exit. Careful.
Wow thanks for the information. Man, i have the thought to invest some of my money a few weeks ago. Luckily, i read this info first before buying. I remember the hype for this token among my friends, but after seeing this reply, i won't bother to buy
