The existing answers suggest that withdrawing from exchanges like Finex or Binance is the best way to get high amounts of Tezos USDT. However, this doesn't necessarily mean that Tezos is 'bad'. It could just mean that the current market conditions are not favourable for Tezos and that it is not performing as well as other cryptocurrencies. Therefore, it is important to consider the current market conditions before making any investment decisions. Additionally, it is also important to research the project and understand the technology behind it before investing. Ultimately, it is up to the individual investor to decide if Tezos is a good investment or not.
