2  Bitcoin / Mining / Is bitcoin mining just completely not profitable for retail? on: May 16, 2024, 10:44:04 AM
Bitmain Antminer KS5 Pro. The state of the art mining rig today, pumps out 21TH of hashrate. You can buy one to receive this month for 30k, or wait until august and get it for a cheap 11k$.

21TH, will make you 1$/day.

That's 27 years for ROI (obviously not because of difficulty and price changes, but let's assume.)

Say you buy 20 of these bad boys.

This is going to set you back 220,000$. For a hashrate of 420 THs.

It will take you 500 days, to be able to accumulate 11k, to add one more miner to your farm.

Remember I am completely disregarding any electricity costs here, just to realize how absurd it all is.

Is there any conceivable scenario, where buying a bitcoin miner today, is more financially profitable than just buying bitcoin?
3  Bitcoin / Development & Technical Discussion / "Trustless Computer" on Bitcoin? Information/opinions? on: May 18, 2023, 12:04:15 PM
I've seen this gain traction on twitter, but I'm here to solicit more opinions and takes from actual bitcoiners.

https://trustless.computer

I have used this just today. The premise is that the dapps are running on bitcoin. But there is a chain on the middle, which is "trustless computer".

The thing is that the transactions for the "dapps" are made on the bitcoin network, so I am not sure how the full details of the decentralization here works. For example, they have a "name system" set up, where I visit the name system "dapp", choose to register a name, connect it to my "trustless computer" wallet, and broadcast&sign a transaction on Bitcoin, to get my "name".

Have you guys ever heard of this? I searched for "trustless computer" and got zero results across the forum.

There was a coindesk article that mentioned this today, which is why I decided to come here.

10  Economy / Collectibles / [WTB] Your cheap collector items (1$ to 999$) on: November 06, 2021, 01:03:51 PM
Hi, I'm not really that interested by rarity, but I want to buy relatively older items that look good.

My only collection so far is a NastyFans coin and I'd like to make that collection bigger.

Don't overcharge me, and consider this post as somewhere to "dump" your items that don't have much of a collector value that might interest me.

You're free to PM me or post pictures here of said items, and your quote for them.

12  Economy / Economics / FTX adds Paypal deposits on: March 02, 2021, 12:12:05 PM
According to their CEO tweet :

https://twitter.com/SBF_Alameda/status/1366614366435483651

1) you can now get *instant* fiat deposits on FTX

2) you can now deposit *any currency*, more or less.  Paypal converts for you.

3) Paypal charges are fees!  If you're doing a large transfer, wires are slower but cheaper.

4) credit card deposits work through it!

It's feasible today through their platform :



What do you guys think?
13  Economy / Reputation / Scammed using Binance P2P, be careful, also looking for aussie to help on: February 28, 2021, 07:35:02 PM
I got scammed using Binance P2P.

The seller's username was chalupa, they had over 500+ trades with a very high "completion" ratio, and a full ID-ed profile. I used Paypal, I know I should have asked for an ID and a selfie to verify the person had the correct details, but I considered the high profile rating something worthy of trust, it wasn't.

Here's the binance profile of this seller :



I think these scammers are running fake account networks, and wash trading between each other to pump up the numbers in the ratings, while in reality they don't really mean much. I made sure to report the profile to support, but I'm making this post to warn other users on here to not trust anyone on Binance P2P, this "selective scamming" problem is extremely hard to pinpoint, because the seller could scam select users and still continue operations that increase their profile ratings for every single scam they pull off. Please only trade in small amounts until you build your own list of trusted people.

Also, I'm trying to recover my funds and if there's any Australian willing to help me out it'd be appreciated, there is someone I need to contact there related to this situation. (I'll leave a tip!) Cheers!

18  Alternate cryptocurrencies / Altcoin Discussion / Thoughts about / risks of WBTC? on: January 22, 2021, 12:07:59 PM
What do you guys think about WBTC? I understand it's a proprietary smart contract under a multisig by multiple entities.

https://wbtc.network/

There are "merchants" that can request access to mint and burn requests, and for each of these requests they need a tx that backs the mint with real bitcoins.

Bunch of examples in the page here :

https://wbtc.network/dashboard/order-book

I want to start using WBTC more because the ethereum network allows for things like liquidity pools, yield farming, lending/borrowing trustlessly with margin etc.. But what are the potential attack vectors here?

You have txes like these :

https://etherscan.io/tx/0xe6f95c38659c5ec6a6886771de2fed8fe4d4876eb8e8fc6a180ad63bf93f400b



So the mint request has an amount, btc address, and txid to trigger the mint. This seems to happen manually, since after the tx above, a few hours later this tx approving the mint is exercised :

https://etherscan.io/tx/0x45efef8f065a365dc1259ea2ff3efc158cde397ae8d45a90115646665555c29f

The question remains in the trustworthiness of these custodians. Taken from their press release :

Quote
T​he WBTC DAO members initially consist of AirSwap, BitGo, Blockfolio, Compound,DDEX / Hydro, Dharma, Gnosis, GOPAX, Kyber Network, Loopring Protocol,MakerDAO, OmiseGO, Prycto, Ren, Set Protocol, and TheOcean. Any critical changesto the WBTC structure must be approved by the DAO.

I understand that more projects makes this more secure as multisig becomes harder to compromise but many of these projects are not worth a lot in market cap and thus makes many of them weak links in this group.

Also, can anyone explain why the number of circulating tokens on etherscan is different from the tokens displayed in the "audit" link?

https://etherscan.io/token/0x2260fac5e5542a773aa44fbcfedf7c193bc2c599

https://wbtc.network/dashboard/audit

On a different note, since all of this is done manually I'm guessing WBTC is somewhat immune to smart contract flaws or bugs, as the contract itself is fairly simple and since all mint txes are done by the same individuals there is lesser chance of that sort of issues happening. But like I said above this also makes it prone to different kinds of issues like social engineering or conflict of interest.

What do you guys think about all this? Do you guys use WBTC? Do you have any other ideas or potential black swans for it?
19  Economy / Lending / Best USD (or any stablecoin) borrow rates against bitcoin on: January 15, 2021, 08:58:09 AM
Hi it's been a while since I posted, I thought this might be the best place to ask
I'm thinking of some reasonable leverage trading but the options have gotten worse over the years
Binance seem to have recently upped their USD lending rates by 20% making it a 36 to 44% yearly rate..
I have looked into smart contract solutions like Dai or Aave, which offer reasonable rates, but I'm still worried about risks such as

https://www.reddit.com/r/MakerDAO/comments/fi832z/im_part_of_makerdaos_bug_victims_and_loose_250eth/
https://www.comp.xyz/t/dai-liquidation-event/642

Basically I dont trust WBTC and dont want to be prone to some stupid risk based on oracles and contravts that have prebiously failed several times
What are my best options? Do you guys know other exchanges that offer reasonable rates?
