I preferred everyone please stay away from this type of trade with anyone. It is not a safest option when you will buy a decentralized wallet it means you buy a share waller there is no gurantee that your funds is safe in that wallet.
Yeah the risk is there because you and the seller have access to the wallet.
I started playing with bitcoin for first time a couple months back and bought like 100 dollars worth and started playing with it and swapping it around till I was left with 13 dollars l, it was a learning experience.
I looked at the address you gave but it doesn't look like you had USDC in there.

I sent a $1.6 worth of ETH anyway to help you out with the gas fees like I said I would. Good luck playing with that.
