1  Alternate cryptocurrencies / Marketplace (Altcoins) / Ada for Eth? on: January 06, 2018, 01:09:13 AM
I really want to get a hold of some Ada, I don't have funds to properly invest right now. Only $3 in Eth, but I'll trade it for $2 worth of Ada. Any takers? Thanks.
2  Bitcoin / Project Development / A continous, conglomerate Bitcoin lottery (need feedback on idea) on: December 29, 2017, 08:25:29 PM
This lottery would not need slots to be filled and it will not always have only 1 or very few winners.

The idea is this:

A lottery game will start after x seconds, and anybody who bought a ticket during that time will be entered. A random number from 1 to the number of tickets purchased will be generated. That random number decides the amount of winners. The pot will be split between the winners, minus 1%. Those winners can then decide whether to carry on the lotto, only 2 people need to decide to keep playing for the lotto to carry on. Whoever is still playing will win the pot plus that 1% from earlier, -1% of their win for the house. If that was difficult to understand there are a few game scenarios I've created below (dollars used for simplicity).

Scenario #1

$1 entry fee

10,000 people enter the lotto, $10,000 pot

Random number from 1-1,000 generated is 100

100 people win $99 each, $100 (1%) is stored

2 people decide to continue playing, each put up their $99

The winner takes 99% of the $198+$100 stored, $2.98 goes to house

This means the winner won ~$298 from a $99 bet with 50/50 odds (if you don't include the odds it took him to get there)

Scenario #2

$5 entry fee

100 people enter the lotto, $500 pot

Random number from 1-100 generated is 5

5 people win $99 each, $5 (1%) is stored

Nobody decides to continue playing, the $5 goes to house

Please give me your feedback, any improvement/problems would be awesome to hear. Thanks.
3  Economy / Scam Accusations / hitbtc is a phishing site on: December 20, 2017, 12:22:17 AM
I have never heard of HitBTC until a few days ago, let alone ever have an account. I got an email titled "Successful Login from New IP", so obviously I go to login and click forgot password. After receiving the forgot password email I put in my email address and a NEW password. After I pressed submit it thanked me for signing up and said it sent a confirmation email. I thought I already had an account that was logged into from Serbia? But no, I just made an account. Now they have my email address and one of my passwords. Also I never actually got a confirmation email so I cannot sign in.
4  Bitcoin / Bitcoin Discussion / Re: How random are TX IDs? on: December 18, 2017, 08:53:30 PM
I want to know if a sender can somehow predict what the last digit will be. Also the only possible combinations are a-z and 0-9 right?

Yes. If the sender has the technical knowledge, they can choose what the last digit of their transaction ID will be.

The only possible values when the ID is in its common hexadecimal representation are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, & f

Although you may also see the alphabetical values in upper case: A, B, C, D, E, & F



Thanks.

What about the last 5 or 10 digits, will there be a point where they cannot have any influence on it?
