No, you did nothing wrong.  The price goes up or down due to the market ... what people are willing to pay for the coin. 

The new team is working on making the coin more attractive to buyers, but that doesn't happen overnight.  To hear what they are doing, you can listen to recordings of the bi weekly community meetings (on the Discord - Community Meetings channel https://discord.gg/z57Bmgx ... or on Jim Hopper's YouTube channel - https://www.youtube.com/channel/UC4r1kfFZ6rezVwAWj0mnaXA) ... or you can come to the next meeting in the Discord General voice channel on Wednesday May 2nd at 9 pm GMT.  There you will hear team leads Habaner0 and Kdog lay out what is going on, after which they open the meeting to questions.
