TODO!!! Even this is hard to find! A clean and minimal one! Why! All we can find are shittly levitating YBCO samples in liquid nitrogen! Maybe because liquid helium is expensive?
First 10T Tape Coil by Mark Benz
. Source. Dr. Mark Benz describes the first commercially sold superconducting magnet made by him and colleagues in 1965. The 10 Tesla magnet was made at GE Schenectady and they sold magnets to research facilities world wide before the team formed Intermagnetics General. IGC and Carl Rosner went on to pioneer MRI technology. Cryptocurrency swapper Updated 2025-07-16
It is basically the same as buying and selling from exchanges for fiat, except that you only get fiat.
Swappers are in general able to receive send coins from any address, including self custody addresses.
Centralized swappers were a good way to workaround the endless Monero bans from exchanges circa 2024, e.g. x.com/cirosantilli/status/1771900725649371240 as they effectively serve as proxies for exchanges that are still legal in other countries.
They will eventually have to ban Monero of course, and then the only way left will be decentralized exchanges.
This leads to a scenario where the only effective way to ban Monero is to also ban all other cryptocurrencies. The question is if countries will go that far or not.

Cool data embedded in the Bitcoin blockchain OnChainMonkey Updated 2025-07-16
From their site:
OCM Genesis is our flagship generative art collection that's set many historic precedents since its launch in 2021. Genesis is the first NFT collection where all 10,000 images and metadata (similar to DNA describing the NFT) were generated using code entirely on-chain in a single transaction on Ethereum. With the launch of Bitcoin Ordinals, Genesis is the first ever collection of 10,000 images to be inscribed on Bitcoin in 2023.
Some of their likely transactions were noted in our list of large transactions: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/payload_size_out e.g.:but we haven't had the patience to index them properly yet. Boring art anyways.
