1  Other / Meta / Suggestions for the Newly Implemented Merit System on: January 27, 2018, 07:58:07 AM
Although, this merit system would prevent many spammers and account farmers on our Bitcointalk, but I would like to give suggestions to make it better-

1. Decrease the merit of people based on negative trust from trusted accounts.

2. Increase the merit of people based on positive trust they get.

3. Instead of giving all the users (initial) merit based on ranks, give merit based on activity.
2  Other / Meta / Getting Mail from Bitcointalk for PM that doesn't exist on: January 07, 2018, 10:58:48 AM
Today I got a mail from Bitcointalk that I received a PM from a newbie member (twicticciade). When I checked in my Bitcointalk messages, there was no such message. Also, when I clicked the link in mail to reply, it says that PM doesn't exist.
Note: I wasn't able to see the message as body of message isn't there in Email.

What could be the possible reason for this ?
3  Other / Meta / Account password hacked on: July 16, 2017, 05:28:03 AM
My account was hacked and two posts were made from it.
Hacker didn't change the password.
I already changed the password now to restrict access to hacker.
The two posts were on these pages-
I have deleted those replies now.

Both of these posts were on these of some application SFCMachine.
I suspect 'Morantis' and 'Mocio' is the hacker since he started both of these threads and replies posted from my account were promoting that thing.

Should I do anything else than changing the passwords?
4  Bitcoin / Development & Technical Discussion / Can we protect Bitcoin from Quantum Computers ? on: February 09, 2017, 10:58:22 AM
We have seen some big moves towards a working quantum computer. Microsoft has predicted that Quantum computers would be available in 10 years.
According to some experts, quantum computer can calculate private key for a Bitcoin address in a minute.

So, what can be done to save Bitcoin from it?

One way could be to introduce larger Private keys. But how would they be assigned to people who are currently using it?

And please don't comment that 'you are thinking about this too early.'
5  Economy / Gambling discussion / Is Chances of Winning in Gambling Higher? on: December 26, 2016, 05:51:01 PM
I just did some calculations. According to them, chances of winning in gambling comes out to be around 75%. Please correct me if I'm wrong somewhere

My assumptions-

I'm considering a case, with zero house edge.
It would be X2 if you win. And you get 0 of you lose.
Each game would charge 1 Bitcoin. Which means, 2 Bitcoin if I win, 0 if I lose.
I have 1000 Bitcoin ( many Bitcoins) in the balance of company X (Gambling Website)
Chances of winning and losing are equally likely - 50%
I would withdraw all my balance as soon as my balance becomes 1001 Bitcoins
I'm betting in two player Roulette. (I'm not talking about any sports bet)

So here it goes,

Here L  represents Lost game and W represents  win.  I'm writing the chances of event occurring in front of it. So, LWW means that I lose first game, and win second and third game giving me a net profit of 1 Bitcoin.

Cases which could lead to 1001 Bitcoins,

W -50%
LWW -12.5%
LWLWW -3.125%
LLWWW - 3.125%
LLLWWWW - 0.78125%
LLWLWWW- 0.78125%
LLWWLWW- 0.78125%
LWLWLWW- 0.78125%
LWLLWWW- 0.78125%

You can further continue this.

This sums up to be 72.65 %

Which means you have higher chances of winning in gambling if you follow these assumptions.

Edit 1: I have considered that you can bet each time exactly 1 Bitcoin.

Consider a case , I lose first game (represented by L), so my balance becomes 999 Bitcoins. Chances of losing first match were 50 %. Now I again bet 1 Bitcoin and I win (Balance becomes 1000) . Now again I bet 1 Bitcoin , I win (balance becomes 1001) . Now I will withdraw all my balance .
So the above event is represented by LWW . Chances of happening of above event is 50% * 50% * 50% = 12.5%

Edit 2 : now I've understood it. Took some help from my friend and after reading your comments .
I was right that probability  that ending up with net profit of 1 Bitcoin (1001 balance) is about 75%.
But there are chances that I can lose up everything.
As someone pointed out here, it is due to binomial variance.
