Hi guys. I am a n00b to options trading, so bear with me if my questions don't make sense.

I read on the net that if I have an asset, and I don't mind holding it, then I can write a call option so that I will either sell the asset with profit or keep the premium if the holder doesn't show up at expiry date. My questions are:

1. Can I write call option on coinut.om?
2. Can I set a premium?
3. Can I set expiry time?



2  Bitcoin / Bitcoin Discussion / Re: A challenge to the idea that no-one can create a good brainwallet on: December 22, 2014, 03:22:43 AM
Thanks @CIYAM for bringing this topic to light.

Brainwallet has its pros and cons, but vulnerability to rainbow tables is not one of its cons. In some cases brainwallet provides the best cold storage method out there in the market (except multisig addresses). I have most of my coins in brainwallet.

You don't need to have a good memory skill in order to set up a secure brainwallet. Here is one technique I use to generate private keys.

1. Get 15 random characters and write them down. I use sha256(of some words I don't even remember), then I took the middle 15 characters of the hash value and wrote them down on a paper and on walls, saved them on my cellphone and on my pc, emailed to myself. I don't consider them secret so I have them everywhere.

2. Choose specific date. (it can be the future)

3. Choose a name. (it can be in any culture)

4. Pick one Special character. (eg =.,?/+*&^%$#@)

5. your lucky number.

6. hash them 3 times.


I don't think this technique requires good memory skills.

Hi there,

I would like to know if there is any Somali bitcoiner here in BTT?

Nxt's killer app is the "transparent forging" technology- which enables it to utilize 100% PoS (the concept pioneered by PPC) while eliminating 51% attack.

Welcome on board. You need to do more post to get out of the Newbie jail.  Smiley

No he doesn't. You just need one post and browse the forum for four hours, then you can post elsewhere.

That is what I am doing now. I've just created my account after several months of reading other people's ideas. I posted my first post, and I am waiting for the four hours to end.

Hi all,
I've searched "pettycoin" through the forum, and I didn't find any comment about it (it seems a new concept to me). I want to post a Youtube link that discusses about it, but because I am newbie, I can only post it in the newbie section.
What do you think about it?
