He is not an alt of kwukduck IMO because kwukduck post about bitcoin's doomsday like there is no tomorrow for it, whereas OP here is still predicting that bitcoin will rise to $21,000 in 2030. He might have took some lessons from him though.  
It would be unwise to think that bitcoin price movements will be that slow. Considering the past movements, I think it can be achieved earlier than 2030. Maybe the target price can be reached by the year 2020-2021 after next block reward halving that will happen in 2020.
