Seriously you believe it and then even post it, such posts are to be ignored at the onset, think logically 500k, how in the world would it be even be possible. Even if you assume some major news comes then also it's not at all possible to achieve it. I am sure he was smoking some high quality weed or meth who knows, as it's looking with August 1st event neutralized we can see 3.5k by the year end logically. But again it depends on many factors.
maybe you are right but i would never be skeptical of any price for bitcoin ever in my life. because simply when price was low around $10 everyone were saying the same as you when someone predicted $1000
then 2-3 years ago when price was dropping down from GOX ATH down to $200-$180 people were saying the same thing as you when someone predicted recovery and $3000
