CMC seem strange to me when it comes to listing exchanges and coins as we have seen in the past that some exchanges and coins are added within a month or even a couple of weeks while others have to wait months before being listed. I really don't understand what the hold up is with adding txbit as it has already proven that it is a top exchange compared to most exchanges out there. Hopefully it won't be too long before we see txbit listed and then hopefully we'll see a lot more growth.
CMC changed their strategy and requirements for listing request since the bull run in 2017. I don't remember when they implemented such changes on their strategy, but likely since the second quarter of 2018. If you were here in 2017 and 2018 (you actually been in crypto longer than me), you did know that CMC was very easily listed new coins in 2017. Consequently, massive scam coins launched and fastly successful listed on CMC. I guess, when crypto cooled down, bearish market came, and CMC finally realised their position in crypto should be built up by new listing requirements in order to minimize risks of scam projects' appearance on their site.
Well I still see pump and dump coins being listed on CMC within a few weeks of them launching. I won't name them here but clearly they are pump and dump coins run by the same dev. I made a tweet the other day asking CMC to list txbit and I got a reply saying that they have received the request and will evaluate the request and that the CMC team will reach out to the txbit team if they proceed with the listing so at least we got some news on the listing.
