How was that not clear, haha? I wanted to just give some context in regards to a place, where it is not silicon valley money and millions spewing around. Sometimes social media manager and someone in charge of these tweets can be just some freelancer and if ICO is successful they would have seen major gains and start feeling greedy because, all of a sudden. It could be that You have 1 year's worth of salary in that coin at this point and writing a tweet...
