Should i be worried for receiveing usdt from a random tron wallet?

Hello everybody. I have received some usdt. More than 500) from a random tron wallet. I have 20k+ of usdt there. Well now 20500+ lol And im worried. Should i be? Like my funds being blocked funds or something

Thats the tron adress i received from. All his txs are weird 3 digits and lots of decimal numbers. High quantity of trx and usdt. A LOT of the withdrawals are to inactive new tron wallets. Deposits are mostly from binance and numbers like 14999. 24999. Etc. Its an old acc with 25k+ transactions. Everything is so bizarre. Its like the mothership of those poison adresses that sent you 1 usdt from a very similar wallet that you justdid a withdraw to.

My funds are on a ledger cold wallet.

Thanks in advance!
