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.
I agree with you. Trading will be primarily options for ETH and BTC. But this does not mean that you do not need to add to the exchange other coins for the range.
Do you mean marketing in stores? Sold only 40% of the exhibited goods? A good idea. Perhaps the developers thought about it.
This is not about marketing. The more coins there are on the stock exchange, the more promising it seems in the eyes of its users. Personally, I will only trade options on ETH and BTC. These coins are of interest to me.
I will laugh hard if your predictions fail to come true and Ripple will trade more than BTC. I think that those coins that have the greatest fluctuations in price will be more popular.
I am willing to bet on money that ETH and BTC even separately will be more popular than Rippl. You will see.
