You're not sending money. You're sending tokens. People who say that they are sending money "on the blockchain" are being disingenuous.
You have to account for transaction fees into cryptocurrency, the blockchain transaction fee itself, and the conversion into the target local currency.
You left 2/3rds of that process out, conveniently.
Then you transfer to Exchange A and sell, and what do you get when you sell? Tether.
The point of Tether initially is regulatory arbitrage for Tether based exchanges. It gives them a fiat substitute without having regulatory baggage that trading in actual money would require.
Tether then turned into a lifeline for a Bitfinex bailout and now acts as a (almost assuredly illicit) liquidity provider to Tether based markets.
The only reason Tether is worth a dollar at this point is because the Tether denominated Exchanges say it is worth a dollar. They are really what backstop Tether now and are fully complicit.
Bitcoin doesn't solve any trust problem outside of how many bitcoins are in each wallet.
Even in the very basic ecommerce use case: buyer purchases item online with bitcoin. The buyer must necessarily trust the vendor to deliver.
There's no recourse outside of the good graces of the vendor. There's no chargebacks or third party mediation.
Thus Bitcoin actually reverses the risk assumed by online purchases from the vendor to the buyer.
This is the reason why Bitcoin is a failure outside of niche grey and black market concerns. It is far worse for the consumer than existing solutions that isolate them from transaction risk, and will usually kick back a small percentage in cash back.
> Broadly speaking blockchain only solves a singular problem: Trust
This is only true in the cryptographic sense when talking about data on the blockchain.
Blockchains do NOT solve any trust problem outside of data on the blockchain, and in real world use cases when we're not dealing with how many coins each person has in a wallet, this is the most important thing.
Specifically your cryptographic tamperproof data on the blockchain is useless if you have bad actors entering garbage data.
It's useless if the data on the blockchain is out of sync with state in the real world.
Even in the internet commerce use case where bitcoin was supposed to take over, once the bitcoins are transferred you still have the unsolved trust issue of verifying delivery.
Saying blockchains solve the trust issue in the real world is disingenuous magical thinking, and I wish people would stop doing it.
> One entity on the cryptocurrency exchange Bitfinex appears capable of sending the price of Bitcoin higher when it falls below certain thresholds, according to University of Texas Professor John Griffin and Ohio State University’s Amin Shams. Griffin and Shams, who have updated a paper they first published in 2018, say the transactions rely on Tether, a widely used digital token that is meant to hold its value at $1.
> “Our results suggest instead of thousands of investors moving the price of Bitcoin, it’s just one large one,” Griffin said in an interview. “Years from now, people will be surprised to learn investors handed over billions to people they didn’t know and who faced little oversight.”
> “This pattern is only present in periods following printing of Tether, driven by a single large account holder, and not observed by other exchanges,” they wrote in their new peer-reviewed paper, set to be published in a forthcoming Journal of Finance.
> “Simulations show that these patterns are highly unlikely to be due to chance. This one large player or entity either exhibited clairvoyant market timing or exerted an extremely large price impact on Bitcoin that is not observed in aggregate flows from other smaller traders.”
Hard to read this as anything other than a sales pitch:
> While a 24% market share — 1 out of every 4 sales in this market — seems wild, the thing that blows the minds of many Tesla Model 3 owners is that anyone is still buying an Audi A4, Volvo S60, BMW 320i, Mercedes C300, etc.
Split keyboards allow you to keep your keep your wrists at a more neutral position vs having your forearms rotated inward but then twisting the wrists outward in order to type on a flat keyboard.. It absolutely helps with my RSI and if I have to use a flat keyboard for an extended period of time I start to get wrist pain.
A split keyboard and ergonomic trackball such as a Microsoft Trackball Explorer or Elecom Deft Pro, combined with a weight training workout, essentially solved RSI for me.
DNS has always been decentralized. I mean, first sentence on wikipedia:
> The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
