Does Trading Bitcoin on Binary option is a Gambling? ?

I would call it speculating, as there is no true way to put a value on a bitcoin. 

Buying Bitcoin is NOT investing.

Bitcoin is used as a form of gambling where buyers hope to sell them for more than they paid. Its value fluctuates daily as its novelty and popularity changes. Unlike corporate stock where a business is earning money or a bond that pays an interest amount, there is no reason to expect Bitcoin to make money for you.

If you wish to gamble, I recommend a casino.

Bitcoin is $35,222 today. Would you be willing to bet that it will be $40,000 in a week or $5,000 in that same week. That is Worse than gambling. And the price alone is fictional since the currency doesn't really exists anyway. 

Unless someone knows something I do not know I consider trading Bitcoin gambling.

I do not consider binary options traded on an American exchange, where you can buy of sell them any time prior to expiration, gambling. I consider trading other types of binary options gambling. (There maybe other well regulated exchange traded options in other countries which I wold not consider gambling, but since I never see them advertised I am not aware of them.)

Both are silly, have not and will not do either.
