I bet most of the users here already know about USDT since its topcoin in coinmarketcap, also most of any crypto trade will use pair /USDT to save their profit to a stablecoin.
Some advise for next time, try to create your own words instead of copy from the source only.
This is not about "do you know USDT", this is about "have you checked my website?" and nothing more than that. OP is clearly just a spammer who wants to both attract viewers to their website but also have their website backlinked from a high level website like bitcointalk so that their website would be SEO friendly and get higher rank on google, that's it. This is not about helping people, this is not even about getting people to read their article neither, it is just about getting backlink and maybe few clicks and that is it.
Unfortunately bitcointalk doesn't have any sort of response to having people spam their website here which means you could actually start a lot of spam topics as long as it is not too obvious, you just need to make sure it looks like you are trying to do something good like "do you know how to use usdt" and if someone blames you with spamming your website, you can defend yourself with "but I was trying to help people learn about usdt" and get away with it.
