First, you have another duplicate [thread] in the Marketplace section. Lock it and move it to the archive, then continue with this active thread.

As for the BTTC token, it is already available on CoinMarketCap [here] - BitTorrent [New].

Regarding purchasing it, it is available on both DEX and CEX platforms, with the most popular centralized exchanges being Binance, Bybit, OKX, and Gate.io. As for the KoinBX exchange you mentioned, I do not recommend using it as the platform shows "Total assets: Reserve data unavailable," in addition to being an unknown exchange. >> https://coinmarketcap.com/exchanges/koinbx

Before using any CEX, you should conduct your own research and review their Terms of Services. Alternatively, you can use a DEX without going through KYC verification.
