Well, it was all clear in the video, if you want to go back and watch it again.
Due to harassment, we stopped the coin sale.
With you trolls bad mouthing a company, its no point.
And now, we save time anyway.
Running a coin sale takes time and resources.
Now instead we let people buy the coins on an exchange:

And we save time.
Now we are free to work more on the website and promotions.
