Also there is a risk that these telegram exchange services can be used by scammers to promote fake exchange projects because there isn't much information available for most of those bot and they can easily be removed by the owner of that bot. Telegram based exchange bots are not very practical solutions that we can see.
Yeah, usually with these exchanges that are found they are not strict with listing. So if it's just a type like it's a dex, then everything is on there and everyone is more prone to the scam listings and tokens that will be there. And aside from the security measures that you're likely to connect the wallet you use like meta mask or so, the chances of you being scammed is high when you're not researching and you just keep with the flow just as what these people telling that there's a hype and trend on it where in fact that there's none.
Is there an option to connect the wallet to those telegram bot exchanges? I don't think so as these exchanges are more likely centralized exchanges, and their users need to deposit their funds at the deposit address where those exchanges keep those funds into their custody. Even though these exchanges give assurance that they are a legit project and have strict security measure still it will not be practical to use as these small bot will not be able to handle big transactions.
