I think your thread isn't appropriate here as this is for bitcoin discussion and not for altcoin ( which is you're talking to )
Just click the move button on the lower left side of the page.
Though anyway, just heard that bitcoin options aside from bitcoin futures.
well, this is not for altcoin actually. This is an options trading for bitcoin. So, strictly speaking, whether you buy call or put, it is all depending on the price of Bitcoin.
And as I thought, bitcoin options is the trend in the near future. It is one kind of financial derivatives for bitcoin, just like bitcoin futures & swap in the last years.
The last, actually, options trading is much safer than futures, because bitcoin options on BitOffer will never request any fee or margin, which means that when you lose, the largest lost will only be the principal (sry that I am not a native English speaker, I hope that you can understand what I mean in principal). But when you win, the profit can be up to 1000X leverage. In conclusion, BTC Options on BitOffer is not so risky actually but it really can let users earn a lot.
Unlike futures, it will request fee and margin, when you lose, you will lose the principal and the margin.
If you are interested, maybe we can discuss more on telegram.
