If strangers offer you to buy something in Telegram, then it is a scam.
Scammers can show you a real WAXP token, but to buy you will be given a link to a fraudulent exchanger, where you will buy a token with the same ticker, but you will not be able to sell it anywhere.
Whenever random person chats me on telegram, I always tag them as scammer even before I reply them, and I don’t even respond to some telegram messages. The strategy which they are trying to use for the OP is kind of different because he was asked to purchase a coin on Bitget exchange, which is a exchange that I know even as I don’t make use of it, but I think Arbitrage won’t be possible there.
Op am sure you will have completed your conversation with the person, I will like you to explain how everything ended, or is the conversation still on? What I just think will happen at the end is that the person will end up requesting money from Op, maybe he will end up sending the Op a link at the end, and will ask the OP to input some sensitive informations.
