Nice of you to try to make up an explanation, unfortunately you're totally off the mark.
The warning about being careful to know which "BIT" your purchasing had nothing to do with Bots. First Bitcoin developed and issued the first coin using the name "BIT", long before they purchased Bots. Cryptocurrency has no regulatory body that negotiates or approves crypto names. Consequently, a number of other coins were later developed that also used "Bit" in their name. The warning is simply that, a warning to be careful that you're actually viewing, researching or buying their coin and not something else.
There's no reason they couldn't mine BIT coins with their own miners. There's no reference to their miners in that PR. This is total fabrication on your part. The section you highlighted points out that BIT (not to be confused with Bitcoin - BTC or Bit Rewards Token - also BIT) started out on it's own blockchain. If you bought BIT, the main way your investment grew was if you kept your wallet open and participated in the mining of new BIT coins (i.e. your investment grew with the value of BIT). Later, they added the ability to hold BIT coins on an Etherium blockchain (i.e. one bit was held as a fraction of an etherium coin). This not only allowed your investment to grow with the value of BIT, but also with the value of Etherium (ETH).
The PR provides instructions for converting from the original BIT blockchain to the Etherium (ETH) blockchain through Uniswap or Binance. Binance is not available in the US or UK.
