Berdasarkan informasi yang saya baca di
https://cointelegraph.com/news/exch-shutting-down-reports-hacked-funds, salah satu exchange yakni eXch dikabarkan mengumumkan akan menghentikan layanan mereka pada 1 Mei, hal ini imbas dari laporan yang menuduh exchange tersebut terlibat dalam kasus pencucian uang terkait peretasan Bybit oleh kelompok Lazarus pada beberapa waktu yang lalu. Mayoritas tim manajemennya memilih untuk berhenti dan mundur karena hal tersebut.
Sumber resmi dari eXch bisa dilihat di sini:

Even though we have been able to operate despite some failed attempts to shutdown our infrastructure (attempts that have also been confirmed to be part of this operation), we don't see any point in operating in a hostile environment where we are the target of SIGINT simply because some people misinterpret our goals. Starting from the date of the merger with a new management team this month, and as a result of some urgent meetings, the majority of us voted to cease and retreat instead of going against strong winds, because none of us want to cause any harm to innocent people or this forum.
SIGNIT = Signals IntelligenceSebagai informasi tambahan, saat ini ada dua perusahaan yang masuk pada kategori 'Alert actors' pada link
https://www.lazarusbounty.com/en/ dimana salah satunya adalah eXch yang dianggap tidak kooperatif dan menolak merespon atas laporan yang masuk terkait dana curian hasil peretasan Bybit.
Saya pribadi sangat menyayangkan sampai terjadi rencana penutupan seperti itu, mengingat dari apa yang saya pahami adalah kesalahan awal terletak pada exchange Bybit yang ternyata sistem keamanannya masih rentan sehingga bisa ditembus oleh kelompok Lazarus. Namun, desakan dari luar pun nampaknya lebih besar sehingga mereka memutuskan untuk menghentikan layanannya.
Bitcoin: Born for Privacy
Satoshi Nakamoto created Bitcoin as a tool for privacy. The entire cypherpunk quest, which Satoshi was an active part of and which the Bitcoin experiment is the coronation of, was all about personal and financial privacy. Most of the early messages and publications by Satoshi (including the famous whitepaper, which devotes a paragraph to it) are heavily concerned with its privacy features.
The first consideration made in the whitepaper about privacy is that centralized online payment intermediaries are easy targets for regulation. As such, it is easy to push these intermediaries to actively mediate disputes and thus to make most transactions reversible. This requirement, as a consequence, forces merchants, scared by risks of chargebacks, to be very “wary of their customers, hassling them for more information than they would otherwise need.” Merchants get pushed back to the “KYC paradox” once again. Being decentralized and impossible to regulate, Bitcoin cannot be forced to actively mediate disputes. For this reason, Bitcoin transactions can quickly become irreversible, making any inquiry into the personal identity of a payer absolutely redundant and unnecessary.
The second consideration concerns the fact that Bitcoin’s base layer (the “timechain,” developed to avoid double-spending without the need of a trusted third party) requires the publication of every settlement transaction, thus limiting the chance to apply the traditional “privacy through obscurity” technique of centralized providers. This limitation is mitigated by the anonymity of the cryptographic public keys, which are intended to be used only once, without any association with identities to work. In Satoshi’s words,
