DISCUSSION- What's your favorite cryptocurrency?

Other than Steem, which is obviously the favorite or one of the favorites of anyone who uses this site, which cryptocurrency is your favorite? And why? What is its use case? How does it impact you personally? Have you made good gains on it? Do you mine it? Do you simply buy it and hold? Do you trade on it to make more? Or are you not even that into crypto aside from Steem?

Personally I've been heavily involved in a new project my team has been working on called "Lupecoin," or $LUPX according to the ticker. We created this token as a "Proof of Friendship" concept and have been working very hard behind the scenes to bring value & use case. Some things we have been working on include a racing dApp, a mobile/desktop wallet, and even an animated video series which is slated to be released sometime soon. If you'd like to know more about Lupecoin, check out our website. Hope you enjoy!!
