The most easiest and most reliable and most importantly attractive idea would be non other than being able to purchase crown directly from the official Crown site.
I would recommend making a link or so so that people can easily purchase Crown currency. Many of you may disagree but if you think deeply and research or visit other cryptocurrency sites. You will notice none of them sell directly. This could therefore be a change or update in the cryptocurrency society.
I have had experience my self, i still have not purchased even 1 crown yet while i was hoping to purchase 100. Sites like Cryptomate tend to not be trusted. Once dogcoin was said to be at the price of $488,808 which from $8.00 went to that much? Ethereum had the same problem stating $11k. (I should of took a screenshot, lazy me).
If this update happens people will find out how easy and less frustrating it is to purchase crown.
