I was looking through 2020 transactions during the recent update. I didn't have any disruption, or see slower speeds, although I didn't do any transactions.

I read the comment somewhere that perhaps Cardano (ADA) was going to get added. That is not the case. As a sidenote, I'm still a little salty, like others that bought BAND to stake, only to find out Coinbase sells the version that cannot be staked. Had I done more research I would have found that out the easier way right? Lesson learned.

The three added cryptocurrencies are SushiSwap, Polygon (Matic), and SKALE Network (SKL). They are currently only listed, but usually when Coinbase Pro lists a cryptocurrency, it is available to buy, sell, and trade within 72 hours.

I am not buying any and don't currently own any, although Sushi got a lot of hate last summer, today it is #6 at DefiPulse. Please be aware that cryptocurrencies may drop in price as people that already own it take profits. That is why some recommend waiting a bit before buying something newly listed on an exchange. The opposite is indeed possible, that it spikes up, but do be aware there are others that might sell to take profits.

I am not affiliated with Coinbase, other than being a user. It would be greatly appreciated if 1099-B's were sent for US users, it would make taxes less of a burden to file!
