That is NOT called delusional, it is called either aspirational or projection or prediction... sometimes it is stated blindly and other times it is stated within a context.  Many of us in the bitcoin sphere expect bitcoin to take off on an upward projection, and some of us are thinking that it may take off sooner, rather than later... so that can be a bit anxious, and maybe even become delusional, if people were to invest at $1200 or some other high amount, and see the price going down, rather than up.. surely there is going to be an up trend it is a matter of when and for how long and how persistent.. those questions are all worthy of different conclusions from different people... since you seem to be in this space to critique the comments of others, what is your aspiration or investment into bitcoin or some other asset?  If NOT bitcoin, then what are you doing, here?  You understand that there is a variety of people here with a variety of perspectives, and what point do you make by criticizing people for saying to the moon?  

Why don't you say:  BUY, BUY, BUY..... and get into the spirit rather than calling people names (such as delusional)?
