I just did the Coinbase earn program for Tezos (XTZ) and I plan to invest in it in 2020. Tezos is one of those cryptos used for smart contracts and I think that will only grow in popularity and adoption as time goes on. They also have a great and somewhat unique voting structure which should help with innovation on this platform in the future. But here is the real (and somewhat shallow) reason that I am excited about buying some Tezos. You can stake it right there on the Coinbase Web site. In fact, they have this little ticker on the site that you can turn on to start staking (which they refer to as "baking) your Tezos and earning more tokens. I just earned about 4 Tezzies from completing the earn program and my little token ticker immediately took off and start earning me more tokens....or at least an infinitesimally small fraction of a new token. It was mesmerizing. I could watch that ticker go up all night. I went to my kitchen got a beer and came back and just watched the ticker increase. There is something fun about watching yourself become richer even if you know it is by a very, very small amount.
Cheers!
