Coinbase is one of the world-leading exchanges has recorded the highest number of listing in 2021 as the exchange has a total of 139 tradable assets, which indicates a high volume of listing in this year 2021.
If coinbase was not doing it and then another cexs will be robbed their daily trade volume. You must always remember that sometimes the volume gets centralized into the some new tokens that have not yet listed in coinbase. You can imagine if CB customer was also moving their money to that token and it's not yet listed in coinbase. That would be a disaster if coinbase didn't actively listing the new tokens on its market. Im so glad that CB has been changing.
This is the reason, it is 100% definitely the reason why we have coinbase listing so much. They went public recently and that means they need to keep making more and more profit. In order to make a lot more profit, they need to offer people chance to buy a lot more coins, all of those trading volumes turn into profit for the shareholders and if that stops then they will end up with losing a lot of money.
Hopefully they will continue to add more coins and features to their exchange, even binance is a lot larger and they are not public company, hell even not legal in some nations. So, I would say that Coinbase has a long way to go but they are on the right path, more profit for them means more options for us.
