coryl··on Bitcoin is none of the things it was supposed to be
I doubt that blockchain was invented by a fresh out of school computer science graduate. The breadth and depth of technical complexity (even if just the white paper) that blockchain covers requires time and experience to accumulate.

Technically they can try, by selling users coin in a fractional reserve model. This is probably already being done by some exchanges.

But that's a problem regarding legal regulation.

coryl··on Bitcoin is none of the things it was supposed to be
The author seems to expect that the changes created by cryptocurrency should be visible immediately. It is a lack of patience, and lack of understanding that changing deeply rooted systems and behaviors takes time.

People have never managed software where if you lost your "password", your money was gone forever. They never had to keep a 12-24 word recovery phrase. They've never sent money to addresses that look like hash strings. Their money value was never this volatile (in some countries anyway) and never this complicated to use (understanding and waiting for block confirmations, looking up transactions in the blockchain explorer).

That's why Coinbase exists, to obfuscate these complexities, to sell security as a service. The cryptography behind cryptocurrencies allows you to basically be your own bank vault; this is not intuitive to people.

The fundamentals for Satoshi's vision have been laid out, the rest of the implementation details will come in time.

coryl··on Goldman Sachs Plans to Clear Bitcoin Futures When They Go Live
Buy and hold doesn't have any recurring fees. If you look at the opportunity cost between crypto and any other financial security in the market, its an easy decision.

Exactly, which is why the safer bet is going long on high market cap coins, not small volume coins where pump and dumps can cause liquidation events.

If you are short term day trading you're likely to be a victim of pump and dump groups and manipulation.

Going long on high market cap coins with a longer timeline is a relatively safer bet.

I suspect the investment banks that say they're going to stay away will quickly get FOMO and jump in sooner rather than later.

Crypto is always in the headlines and will constantly occupy the headspace of trader's colleagues and peers, so it's just human nature that they will not be able to resist having a taste.

coryl··on Ask HN: P2P crypto exchange - possible?
By peer to peer exchange, you mean an exchange built on blockchain?

One exists that I know of (bitshares). I'm sure others are being developed.

Turning fiat into crypto is a separate problem of its own. The problems there are legal and political, not so much technical.

coryl··on Ask HN: How do we know Bitcoin is not in a bubble?
It probably is a bubble.

The problem is when it bursts, we don't know if we'll be in better positions having entered now, or having entered after.

coryl··on Ask HN: What is driving cryptocurrency value?
You don't use it in individual transactions.

It's for wholesale drug operations. Usually drugs go at one time, money comes back another time. Only now instead of cash you could just use a crypto, but figuring out how to liquidate enough of it would be difficult.

coryl··on Understanding Ethereum Smart Contracts
I'm using web3 1.0.0-beta.26, ganache-cli 6.0.3

I instantiate the web3 object as such: web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

When I try to setup an event listener, console logs this:

Error: The current provider doesn't support subscriptions: HttpProvider

coryl··on Understanding Ethereum Smart Contracts
You can use a test node called testrpc (now called ganache-cli ???) and connect to that.
coryl··on Understanding Ethereum Smart Contracts
I've also just begun to play with smart contract programming.

One problem I'm having is with event listening.

It seems that MetaMask doesn't yet support subscriptions, nor does my localhost testRPC instance pass it in the web3 object.

Some have suggested I need to run my own node just to listen for contract events. Has anyone figured out an easier solution?

coryl··on The Bear Case for Crypto, Part II: The Great Bank Run
Why does he need to call you back? Stock market crashes are nothing new. Bitcoins are basically the same thing as stocks in terms of the way they're traded.

No one is saying a price crash isn't possible. But it won't be caused by some liquidity issue, it'll just be people selling off.

coryl··on The Bear Case for Crypto, Part II: The Great Bank Run
Ok, so the problem is in the legal arena; the government bans banks from allowing cryptocurrency transactions.

This doesn't seem like a fundamental problem due to the structure of Bitcoin or exchanges.

coryl··on The Bear Case for Crypto, Part II: The Great Bank Run
So wherein lies the liquidity problem?

I deposit USD to an exchange...then use that USD to place a Bitcoin buy order. Then I sell some Bitcoin another buyer on the exchange, who was only able to make this transaction happen because they too deposited USD or fiat into their account.

I get the money, they get the Bitcoin. Who is getting screwed?

coryl··on The Bear Case for Crypto, Part II: The Great Bank Run
Fractional reserve systems have fixed maximum supply of currency?

According to the Bitcoin protocol, only a maximum of 21m BTC can exist. And that they are created via mining in a predictable schedule.

Respectfully, I think you need to revisit Bitcoin fundamentals.

coryl··on Ask HN: IF the Bitcoin bubble bursts, where would you invest next?
It's not that Syrians distrust the Internet. Its that they distrust their governments and politicians. And possibly their banks.

There is already a lack of legal systems and order. You have ISIS roaming around cutting people's heads off.

Obviously you have a different set of priorities when you're running for your life.

coryl··on The Bear Case for Crypto, Part II: The Great Bank Run
I have a share of AAPL stock. I wish to sell it.

I place the sell order with my brokerage, and I get fiat USD deposited into my account. This is exactly how Bitcoin is exchanged.

Where exactly lies the fundamental liquidity problem for my brokerage/exchange?

coryl··on Ask HN: IF the Bitcoin bubble bursts, where would you invest next?
In due time. Commercial transactions will occur first, business to business.

Consumer applications (like Coinbase) will emerge to support the local population who can use it via smartphone and not need to understand public/private key encryption etc.

how would you get a meaningful number of people who have never used the Internet

They use the Internet; they just call it by a different name: Whatsapp, Facebook, Instagram...

Why would a person with low wealth invest their life savings into a highly volatile, recently developed instrument, when they can just buy jewelry, gold, etc

Gold, jewelry, etc can be stolen or lost.

coryl··on Ask HN: Non-technical day trading strategies?
Thanks, although I believe Buffet's general strategy is to buy undervalued businesses for the longer term.

I was hoping for day trading strategies.

coryl··on Ask HN: Non-technical day trading strategies?
Hey, thanks for replying. I am the same person.

I'm not really asking how to time buys and sells. I'm asking for models or strategies that traders might use alternatively to graph reading. Ex. event driven strategy (trading on news and rumors).

coryl··on Ask HN: Non-technical day trading strategies?
Many investments do not generate income, and the profit is made from the appreciation of the asset (ex. A Da Vinci painting, or gold).

You can make a profit off of the mispricing and misjudgment of others.

Better knowledge exists in many ways, not just insider news/current events. Example: I understand what hashing algorithms are, the difference between Proof of Work and Proof of Stake, therefore I may be better at judging the feasibility of a cryptocurrency and thus better at valuing it.

coryl··on Apple’s diversity chief out after outcry
I suppose as the saying goes, one man's civil rights activist is another man's racial extortionist.
coryl··on Apple’s diversity chief out after outcry
Racial extortion...interesting term, haven't heard that one before.

At this price point, the target market probably isn't prioritizing for usefulness / raw utility as a purchasing criteria.
coryl··on Ask HN: Is short term crypto currency trading profitable?
There's enough volatility to make it extremely profitable.

Coins are going up and down 10-30% for no "real" reasons.

coryl··on Social-Media App Musical.ly Is Acquired for as Much as $1B
Do music/entertainment companies even scout anymore? Seems like a redundant role, given music publishing is largely dying out as well.
coryl··on Show HN: Mental Modelist – App Store for Mental Models
Short paragraphs on major concepts, graphs/visuals. I'm sure there's a common formula for developing good summaries.
coryl··on Show HN: Mental Modelist – App Store for Mental Models
Would be great if the summaries were actually summaries. I'm guessing this is just a proof of concept though? I like the idea.
