Where should I start?
1) Is Blockfi profitable?
2) How much money does BlockFi have on its balance sheet?
3) Is the yield that BlockFi pays to its depositors earned or subsidized by billionaire investors?
4) Has BlockFi ever been profitable?
5) Are you planning to go public?

Go to 1-4 hour chart.

Use the following EMAs.
13,21,50,180.

Look for a period of consolidation and
13>21>50>180.

Wait for a pull back to 13EMA.
If bounce occurs with volume, Enter.

Exit on bearish cross with 21>13.

Options used to be close to irrelevant for bitcoin's price.

Until now.

At current price levels, hedging large option notionals has a major impact on price.

Here's a quick thread on options 👇

Let's start with the meaning of delta.

Delta is the rate of change of an option's price relative to a change in the price of its underlying.

For example, the price of a 50 delta option will move 50% as much as the underlying.

For practical purposes, think of it as how much of the underlying you have:

- if long 50 delta call on 1 BTC => long 0.5 BTC
- if long 50 delta put on 1 BTC => short 0.5 BTC
- if short 50 delta call on 1 BTC => short 0.5 BTC
- if short 50 delta put on 1 BTC => long 0.5 BTC

An option where the option's strike (i.e. exercise price) is equal to current spot price is known as an at-the-money option (ATM). ATM options have a delta of 50, while deep in the money options have a delta of close to 100.

Can also think of delta as probability. A 50 delta option has a 50% chance of expiring in the money.

For a call, the higher price goes => the more in the money the call => the higher the delta.

Once delta gets close to 100, odds are ~100% the option will expire in the money.

Some thoughts on this super inaccurate piece.

tl;dr: this is not a defence of Tether/ iFinex, who I would like nothing more than to see disappear into irrelevance. However, most of the conclusions here show zero understanding of crypto market

1. First up: it’s completely inexcusable that Tether refuse to have a 3rd party audit. I can’t find a single good faith reason for this.

Bitfinex GC recently did a superb job of sidestepping that question on WBD:

2. For better or worse, USDT (tether) started as a way for people to move fiat between exchanges (a major problem) in the absence of the ability to onboard banking partners, none of whom wanted to touch crypto. USDT is now the dominant stablecoin by mkt cap & liquidity.

3. As a result of the difficulty of having a fiat on/off rail, many exchanges, like Binance, chose to be ‘crypto only’, using stablecoins in lieu of fiat. This is why the majority of inflows into BTC (article says 70%) is via USDT

4. Unbanked exchanges are in aggregate larger than banked ones. This is true, but it’s not because of a giant conspiracy to steal your BTC. Being unbanked = real regulatory arbitrages (lower cost + ability to innovate fast), and lower barriers to entry means there’s more of them.

Back with another #FreeLoveFriday. Last time, we covered how Mastercoin/@Omni_Layer pioneered digital asset issuance on blockchains. Today, let’s discuss @Chainlink and the vital role it plays in connecting blockchains to the real world.

Back with another #FreeLoveFriday. My first thread focused on what I love about Bitcoin, and features we borrowed for @AvalancheAVAX. Today, let's focus on @Omni_Layer, or as OGs knew it, Mastercoin https://t.co/fXFgmaeUEz

I have said repeatedly that digital asset issuance is the killer application for blockchains. The next frontier is bringing real world assets to networks like @AvalancheAVAX, but we often face a significant problem:

Namely, how do you get data from the real world onto blockchains and into applications running on them? More critically, how do you achieve that securely and transparently in real-time? Smart contracts are tamper-proof, but they're only as reliable as their input data.

Enter ChainLink in September 2017, with a whitepaper outlining a vision for a decentralized network of “oracles,” entities that inject facts from the external world into blockchains in a suitable format for smart contracts.

Until ChainLink, oracles were trusted and centralized. This is a huge problem for high-value assets and smart contracts. High value projects, such as @CelsiusNetwork, @synthetix_io, @Aaveaave and others depend critically on oracle data.

0/ Yesterday was my last day as the Rosetta Technical Lead at @coinbase. Starting tomorrow (crypto never sleeps, right?), I’ll join @el33th4xor, @kevinsekniqi, and the rest of the talented team at @avalabsofficial in building @avalancheavax.

1/ When I joined Coinbase out of college, I thought I “knew” blockchain. Boy was I wrong! Standardizing and scaling asset addition at Coinbase while collaborating with the top blockchain engineers at the top projects by market cap flipped my world upside down.

2/ I don’t think there is any other place that ramps you up into the magical moon math of crypto as fast as @coinbase and I firmly believe it is the best place for any crypto engineer to start their career. Good news! They're hiring!

3/ To all my former coworkers, I want to say thank you for everything you’ve taught me. I’ll never forget all the time and energy you spent helping me become a better engineer and a better person. I have no doubt that you’ll continue pushing Rosetta forward for years to come.

4/ For the next few months, I’ll remain an advisor to the Rosetta project. I will lend a hand to asset issuers implementing Rosetta for the first time and chime in on high-level design decisions.

In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.

In the Spring of 2017, after a deep dive into the Fake News phenomena, the security team wanted to publish an update that covered what we had learned. At this point, we didn’t have any advertising content or the big IRA cluster, but we did know about the GRU model.

This report when through dozens of edits as different equities were represented. I did not have any meetings with Sheryl on the paper, but I can’t speak to whether she was in the loop with my higher-ups.

In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.

I think a plausible explanation is that whatever Corbyn says or does, his critics will denounce - no matter how much hypocrisy it necessitates.

One of the oddest features of the Labour tax row is how raising allowances, which the media allowed the LDs to describe as progressive (in spite of evidence to contrary) through the coalition years, is now seen by everyone as very right wing

Corbyn opposes the exploitation of foreign sweatshop-workers - Labour MPs complain he's like Nigel

He speaks up in defence of migrants - Labour MPs whinge that he's not listening to the public's very real concerns about immigration:

He's wrong to prioritise Labour Party members over the public:
