Somehow new coins will be added very slowly. It seemed to me that this would go much faster. There is not even worth offering your coin for placement.
I think that the developers were reinsured and wrote a time margin in the roadmap. In fact, they can add the ability to trade options for new coins much faster.
Add a new coin to the exchange is not so easy. It is difficult and long work. Perhaps this is why it takes so much time.
The listing process itself is not very long. Top exchanges charge a lot of money for listing. Now to get to the top of the exchange if such fees ico mildly profitable.
New exchanges place popular coins for free in order to lure users to themselves.
Large exchanges add dozens of coins per month. So it's not that hard, is it? If there is a desire, there is always the opportunity to hire more programmers and other employees.
On the new exchange there are enough options for 2 coins, these are ETH and BTC. 90% of options trades will be held only with them.
