Fair points, in future articles we will include criticisms and see if we can find solutions for them, and if we cant find solutions we'll report on them too. On second thought the article is a bit too positive and should have a more critical light.
I should of of been clearer on what I mean for holding periods. I believe that LISK can easily be a very long term hold, upwards of 10 years (assuming the government doesn't destroy cryptocurrency). I do also however believe that if someone wanted to do a more medium length trade on this then they could exit around the time of SDK launch and rebranding, since a fair amount of crypto can revolve around the idea of buying the rumor and selling the news.
