It seems clear that you haven't reviewed the links I provided. You appear to be promoting this exchange ^{[If I'm not mistaken]}, which has already been flagged as a deceptive site by the OKX extension. [Talkimg]

Anyway, BTTC is the new version of BTT after the migration, and $BTTOLD is no longer available on centralized exchanges following the redenomination plan. It's only available on DEXs like PancakeSwap, but I don't recommend buying it as it's now abandoned.

This will be my last post on this topic, as I've clarified everything. Avoid falling victim to a scam after all this.
