1  Alternate cryptocurrencies / Altcoin Discussion / Is LAT token a scam? on: October 27, 2017, 04:25:11 PM
LA Token, they promised high and we bought for as much as $0.45 each.
When it was listed on exchange it started trading at $0.2   Why pay more at ICO, i don't understand.

3  Bitcoin / Development & Technical Discussion / bitcoin address question on: September 28, 2017, 12:06:16 PM
While i have been dealing with bitcoin trading for sometime the following question keep bugging me all along. Hope one of you can clarify it for me.

I understand that bitcoin is decentralized and self maintained in the sense there are no central authority to create users or provision passwords or maintain servers.
I also understand that bitcoins are stored in wallets, which are essentially public key hashes aka an address of 20 bytes randomly generated address. To make any transactions on this wallet/public key address  bitcoin decentralized application need corresponding private key.


All well and good. Now my question is

1) How and who generates these public/private keys. I assume anyone can generate ..but whats the criteria
2) Who keeps track of which public keys are generated and what is its corresponding private key .. as far i understand there is no one so i wonder how it works
3) If it is a random public key with no one keeping track of addresses in use, how does the system ensure same address is not being used by two different people. i.e how do we know the key generate has produced a key that is not already in use
4) we keep hearing suggestions about disposing keys and keep creating new ones for security reasons. While it is secure to move on to new address as frequently as possible, my question is how sustainable is this approach. How big is the address space and whats the chance of exhausting the addresses and stumbling on reused addresses.


Some of these questions might be silly to few of you but its better to get clarified than working under assumptions. As you can tell i am a IT developer hence the questions from my developer mindset.

Thanks in advance..
4  Other / Beginners & Help / Merchant help on: September 28, 2017, 11:41:34 AM
I read somewhere the benefit of accepting bitcoin for a merchant is as below

"Convert 100% of the sale to the currency of your choice for deposit to your account, or choose to keep a percentage of the sale in bitcoin if you wish to begin accumulating it."

Can someone please elaborate on how this works. Right now, lets say i have my bank who provides the card processing service will settle my transactions to my bank account periodically.

In that context, how does the above benefit apply?
5  Other / Off-topic / Google Authentication question on: September 28, 2017, 11:38:09 AM
I linked my coinbase and bittrex for 2FA using google auth on my android phone.

Now, i have faced issues with my phone many times and there is a chance you could loose your phone. Now that you can't log in to your coinbase or bittrex without google 2FA, what happens when you loose your phone or you reset your phone?
6  Alternate cryptocurrencies / Altcoin Discussion / Is SIA still relevant on: September 01, 2017, 07:16:29 PM
FILECOIN is a huge hit and has the backing of who is who of the industry.
With a bit unorganized team like SIA, do they have a chance.. i am concerned if i still keep my investment in it intact. Of course same goes with STORJ.

Whats your take on it.
7  Alternate cryptocurrencies / Altcoin Discussion / What is your take on deeponion on: September 01, 2017, 02:48:16 AM
Pump?  They are comparing it to XMR but it being on TOR, i doubt it gets wide adoption.
What you think?
8  Alternate cryptocurrencies / Altcoin Discussion / Whats ETH value based on on: August 31, 2017, 05:11:55 PM
I understand that there are certain amount of BTC ever to be in circulation. when more people want it (due to limited supply) as store of value or transacting currency, it creates demand and drives the up.

what i don't understand is , how is ETH value determined. Its not currency but a smart contract platform. So how and why there is value to ETH and what does it produce to gain value in future.
9  Bitcoin / Development & Technical Discussion / How to get involved to understand crypto world on: August 31, 2017, 04:54:10 PM
Hi,

I am a IT developer with quite a bit of experience but never paid attention to development aspects of crypto/smart contracts. I have been playing with BTC and ETH for sometime so i do understand from the currency aspect of it.

Now i want to get involved with the development aspect of it to get to the details of the technology and to unlock the opportunity it has for a tech developers like me.

Can you share your thoughts how one could travel the path and where to start and what to follow. I am sure there are many like me and a healthy discussion would be very helpful for many.

If there is was a discussing in this line and provide answers to my questions please point me in that directions.

TIA
10  Bitcoin / Bitcoin Discussion / Who is buying bitcoin and crypto on: August 28, 2017, 08:59:41 PM

People that are smart and rich or people that are unproven and hoping to get rich quick

People that are adding meaningful value to society or People that are just piggybacking on someone else's efforts


Just curious...
11  Economy / Exchanges / Best deposit method on: August 26, 2017, 03:51:29 PM
Currently for a USC, as far i know, coinbase and kraken are only possible deposit gateways for fiat to crypto world.

While i have been using coinbase, they have become a pain. Their system blocks me from placing a buy order asking for ID verification, which i have done 1 month back.
When i upload my drivers license and selfie, it just says failed. No details, no explanation, no followup on how to proceed from there. Drives me nuts. 0 customer satisfaction rating if it is in traditional market space. Customer service is absolutely terrifying but i don't see other options.

Kraken is outright asking for SSN,  give me a break. You are not regulated by any authority and your practices are questionable like any other crypto organization. Submitting DL itself is a stretch for me , forget about SSN.


How do you guys convert fiat to crypto and how you are able to overcome these hurdles to quickly deposit when you want.

BTW, i use Polo and Bittrex for buy/sell but only after you purchased your BTC/ETH/LTC  from coinbase.  Appreciate any reliable suggestions that you have tried.

12  Alternate cryptocurrencies / Altcoin Discussion / CENTRA CTR - Is it a scam? on: August 25, 2017, 03:00:04 PM
Dipped my toes with CENTRA ICO, but lot of red flags for this ICO. I took a chance but scam alerts all over for this token.
While investigating their ethereum  contract i found information as attached.

Why is the token limit so high .. what is the correct token limit for CTR?  Their website says its 100,000,000  but the contract shows way different number.
Can someone throw some light on this ...

For some reason i couldn't find a way to attach the image of contract.

Thanks
