i think your going to be seriously disappointed,and based on how conservative their dev team has been to not over valuate the price , i highly doubt they approve a ADA listing when development wise they are a long way away.
I hope your right as i'll make a good amount of money if they do.
Going by the criteria coinbase listed on their site, Cardano is one of very few that fit. But even if Ada is not listed we will make a good amount this year. I promise!
I tend to agree with you here regarding ADA! It may be listed on Coinbase one day, but that day is long in the future. Who knows what will happen to this coin by that time. I actually love the technology of this coin. We shall see!
