I think immediately of the Miami convention several years in the past-where XPY(Paycoin) was the star of the convention. At the time, I was a passive partipant in the XPY community-although, I purchased mining equipment from their GAWminers website and also participated in their POW stage. Therefore, the Miami convention was an excellent form of promotion for XPY. Of course, we all know what happened to XPY.
At the same convention, Vitalik Buterin was promoting his Ethereum. Unfortunately, Vitalik nor Ethereum was in my vocabulary. Therefore, his presence and his product was ignored by my person-and overshadowed by my affiliation with XPY. Had I channeled my attention to Vitalik and Ethereum at that point, I would have affiliated with the proper crypto-token and community.
In summation, XPY has expired and Ethereum is definitely a crypto-token designed for the future.
