1/ The #Bitcoin bear case has two two components:

The macro, and the miners.

THREAD 👇

2/ On the macro side, if the dollar reverses its major downtrend and/or real rates turn positive, that will hurt $BTC considerably.

I don't expect either to happen in 2021, but have to pay attention to these.
3/ On the miners side, one has to consider the miners' cycle.

It works like this 👇
4/ Miners' hashrate (the aggregated bitcoin computing capacity) is directly tied to mining difficulty, which is the main variable in the bitcoin cost of production

=> the more capacity installed, the higher the difficulty, and the higher the cost.
5/ In a bull-run, miners' hashrate lags price, so as price takes off and moves higher, miners' profitability explodes (as price goes up but production costs don't as much).

These are the happy times.
6/ Higher profitability drives miners to increase capacity, and attracts new miners.
7/ Around major tops you will see people who don't understand bitcoin pull online calculators --which ignore other costs such as cooling, pool fees, warehousing, security, and personnel-- and imagine they are going to become wealthy mining bitcoin. Then go buy overpriced miners.
8/ It's important to understand that Bitcoin mining presents a perfect Prisoner's Dilemma.

Here's an old thread on that topic. Mind that the bitcoin produced a month is now 27,375, or about 900 a day. This quantity halved in May.

9/ Higher profitability drives increasing mining capacity, but this new capacity can take months to install.

That's why hashrate increases lag price increases.
10/ Currently, and due to chip shortages related to technological changes and covid supply chain disruptions, delays are in the order of 6-10 months.
11/ While miner profitability moons, miners are capable of hodling more: they can reduce sales to take advantage of rising prices in a bull market.

This adds to reflexivity and helps prices further up.
12/ Eventually hashrate catches up with price. Happy times end, and miners have to increase their selling volumes to pay the bills.
13/ There's another game theory component: if you are a miner and know that other miners will soon be forced to increase their selling volumes, you may want to sell before and front-run them to get better prices.
14/ This increase in selling can be augmented by prior hodling, resulting in a perfect storm.

Miners did hold inventories back late 2020, but their selling volumes have already increased in 2021, with price in the 30s-40s.
15/ Finally, consider that at current prices the dollar amount for new bitcoin produced is considerably larger than it was prior to the halving.

1800 bitcoin/day * $10,000 = $18,000,000/day

900 bitcoin/day * 35,000 = $31,500,000/day
I remain bullish, but it's important to keep the bear case in mind. Miner flows make sure price can't move in straight up lines for too long, and are the reason one should not be too bullish later in the year. At some point miner excesses must be rinsed out.
For those asking where to find miner data, there are three main sources:

@glassnode

All require a subscription unfortunately.

I mostly use CryptoQuant: https://t.co/AaOPJjxt7h

Their founder @ki_young_ju shares very useful data on Twitter.

क्या आप जानते हैं कि क्या है, पितृ पक्ष में कौवे को खाना देने के पीछे का वैज्ञानिक कारण!

श्राद्ध पक्ष में कौओं का बड़ा ही महत्व है। कहते है कौआ यम का प्रतीक है, यदि आपके हाथों दिया गया भोजन ग्रहण कर ले, तो ऐसा माना जाता है कि पितरों की कृपा आपके ऊपर है और वे आपसे ख़ुश है।


कुछ लोग कहते हैं की व्यक्ति मरकर सबसे पहले कौवे के रूप में जन्म लेता है और उसे खाना खिलाने से वह भोजन पितरों को मिलता है

शायद हम सबने अपने घर के किसी बड़े बुज़ुर्ग, किसी पंडित या ज्योतिषाचार्य से ये सुना होगा। वे अनगिनत किस्से सुनाएंगे, कहेंगे बड़े बुज़ुर्ग कह गए इसीलिए ऐसा करना

शायद ही हमें कोई इसके पीछे का वैज्ञानिक कारण बता सके।

हमारे ऋषि मुनि और पौराणिक काल में रहने वाले लोग मुर्ख नहीं थे! कभी सोचियेगा कौवों को पितृ पक्ष में खिलाई खीर हमारे पूर्वजों तक कैसे पहुंचेगी?

हमारे ऋषि मुनि विद्वान थे, वे जो बात करते या कहते थे उसके पीछे कोई न कोई वैज्ञानिक कारण छुपा होता था।

एक बहुत रोचक तथ्य है पितृ पक्ष, भादो( भाद्रपद) प्रकृति और काक के बीच।

एक बात जो कह सकते कि हम सब ने स्वतः उग आये पीपल या बरगद का पेड़/ पौधा किसी न किसी दीवार, पुरानी

इमारत, पर्वत या अट्टालिकाओं पर ज़रूर देखा होगा। देखा है न?

ज़रा सोचिये पीपल या बरगद की बीज कैसे पहुंचे होंगे वहाँ तक? इनके बीज इतने हल्के भी नहीं होते के हवा उन्हें उड़ाके ले जा सके।
The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.


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.
