That is true, the volume on txbit is low at the moment however it is very hard for new exchanges to attract traders to start trading on their exchanges. txbit has listed some popular coins but still it hasn't attracted people to come and trade on txbit. I think that it will take a good 12+ months before we start to see more trading volume and remember that CMC are yet to list txbit which can help once they list txbit.
Binance did not need to much time to take over both Poloniex and Bittrex. Crypto exchange is a highly competitive industry, but to be successful new exchanges do not only need time, but also need effective marketing. That is likely what txbit.io has been lack of months after its birthday. Another minus point is txbit.io has not yet listed on coinmarketcap.com. Visitors might hesitate to join exchanges that are not listed on CMC.
You are correct in assuming that lack of CMC listing is hurting us. We even missed out on multiple projects deciding not to get listed on Txbit because we are not on CMC yet.
But, the Binance comparison is not right. They released at the right place and the right time. The end of 2017 saw a massive influx of new people entering the crypto space, but since then the user count has been dropping hard and the interest is nowhere near the same. There is no new blood entering the space at all right now.
