1  Economy / Currency exchange / 50 USD BTC for Paypal or NEFT on: August 15, 2018, 07:36:14 PM
I am looking to buy $50 BTC for Paypal. I know my account looks new but the last one was hacked so can't help it.

While I don't plan to chargeback but to stop people from explaining it again in the comments here are the major points:
a. I am new on this forum.
b. This an Indian Paypal account. So no, I cannot send you money as F&F. All payments will be as Goods and services.
c. Goods and services payments are subjected to reversal.
d. I am new.


2  Alternate cryptocurrencies / Altcoin Discussion / Re: Robinhood Crypto Trading on: February 01, 2018, 03:52:33 AM

This is just a random person's opinion on the topic, but it's always good to hear different opinions from your own. I decided to read through the article and basically the guy concluded that Robinhood will likely the the BEST place to buy crypto from in the near future. His article just touched on some points for why it could hurt rookie traders that just use market orders and he questioned if they would be able to handle the influx of new users for crypto. He did fail to mention that it is only rolling out in 5 states to begin with so there wont be nearly as high of a number of signups as it says on the waitlist page until it is rolled out to more states in the US.

It seems our conclusions are quite different. There is lot of information but maybe not explained very well.

For one, Robinhood's apparent use of the word "market order" is confusing even for a non-rookie. I personally have never seen people saying market orders but actually it was a limit order. What are other exchanges/markets which does this?

Second, Robinhood not having it's own exchange market is worrying because they have to rely on latency between their platform and the connecting exchanges. So only limit orders which are far out/in the money will work well. If the  market is moving too fast this is a recipe for disaster.
On the same topic, if the exchanges are down, something which happens quite frequently, Robinhood is going to be out of commission too. So the reliability is also questionable.

This might not be as great news as every one thinks:

Well they are not really an exchange.
https://techcrunch.com/2018/01/25/free-cryptocurrency-trading-app/

says:

When you place a buy or sell order, Robinhood gives you an estimated price, connects to a slew of trading venues, exchanges, and market centers to find the lowest price, and uses its economies of scale to improve to score better prices over time. To counter market volatility, Robinhood puts a “collar” around your trade so if it can’t execute it at close to the estimated price, it waits for the price to return or lets you know.


Anyone knows what these exchanges might be? they are also showing prices for other currencies. Any ideas on how those prices are being derived.

They are currently showing prices for bitcoin etc. Anyone knows what is the source of this price feed?

What is the exact distribution for EOS? Is block.one reserving some of the token supply for development purposes?
7  Alternate cryptocurrencies / Altcoin Discussion / List of accounts for an asset on NXT and OMNI on: January 17, 2018, 06:59:46 AM
Is there a way to see all the accounts holding a particular asset? It is easy on Ethereum but I am hitting a roadblock on trying NXT or OMNI platform.

for NXT, I am using the mynxt blockchain explorer. So, if look at Ardor, this is the page for tokens:
https://www.mynxt.info/asset/12422608354438203866

On clicking the "number of accounts" link gets me nothing.

Similarly for OMNI, the https://omniexplorer.info/ has a property statistics link under "Smart Property". It redirects me to this link:

https://omniexplorer.info/spstats.aspx?sp=1

and the page is just a runtime error.

^^ Thanks for the explanation.

Someone please help me with the sizes of different transaction. Assuming 2 inputs and 2 outputs:
Basic - 438 bytes (https://bitcointalk.org/index.php?topic=1782523.0)
P2SH or Pay-to-Script-Hash - Same as P2PKH?
Multisig -  ?? (
RETURN - ??
Non-standard -  ??


And additionally, how much space if any does Segwit transaction save over the current ~ 438 bytes?

9  Bitcoin / Development & Technical Discussion / Re: Types of Different Bitcoin Transaction and Their sizes on: December 26, 2017, 09:06:33 AM
As at 2015/2016, there are five standard transactions which are accepted by the standard client which include Basic, P2SH or Pay-to-Script-Hash, Multisig, RETURN and Non-standard – although some miners will accept a non standard transaction for a price. The most popular type of transaction is the TX_PUBKEY, or Pay to Public Key Transaction (P2PKH) with over 89% of total transaction as at 2015.

The latest transaction type  as at 2017 is SegWit


Thanks. I found a link which says there are 6 types:
https://www.cryptocompare.com/coins/guides/what-are-the-bitcoin-transaction-types/

What is the difference between Pay to public key vs pay to address?

What is estimated size of each type? Here's what I found:

Basic (P2PKH) - assuming 1-2 inputs and two outputs - 438 bytes ( https://bitcointalk.org/index.php?topic=1782523.0 )
P2SH or Pay-to-Script-Hash - Same as P2PKH?
Multisig -  ??
RETURN - ??
Non-standard -  ??
Segwit - ??

I found this interesting take on bitcoin transaction type trends from 2015: https://tradeblock.com/blog/analysis-of-bitcoin-transaction-size-trends

As this is from 2 years ago, I am wondering:

a. Are there any newer transaction types?

b. What is the average size of each of transaction type?

c. Is there a site/way to see the number of each transaction type included in each block?
