First of all, you didn't predict shit when the price was 20k if I remember correctly the highest price Bitcoin got to in Jan 2018 was around 17k, also just to make things clear this was not your prediction alone Tradeview was full of prediction similar to yours and most of them published near the end of 2017 so your predictions can be possible or are probably just a copy past from them and last thing since you are that awesome why you don't go short Bitcoin on any platform that allows that and make a fortune instead of wasting time here. 
Did you buy your lambo? ROFL. Drick heads like you are good for nothing. Go and check my posts and my predictions. Many people thanked me and all the people who argued with me during that time now disappeared or find the bridges to jump as they made a huge mistake believing in this garbage called crypto. ROFL
