Do not be surprised if you do not see the site accessible on May 1. You can see their announcement here on this forum on their service thread:
eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20Know that Lazarus group has been a threat to everyone even to sites that have signature campaign on this forum. Remember they were responsible for for Sinbad shutdown and now responsible for the shutdown of eXch. eXch was reported to have been used by Lazarus group in laundering $35 million worth of coins from the $1.4 billion Bybit hack. eXch said only little amount worth of coins is linked to Lazarus group.
Be out linked to the hack or not, or maybe the coin that eXch processed for the hackers is not up to the investigated amount, we just know that Lazarus group is responsible for what that happened.
That why it alway adiviseable to always stay vigilant and take necessary precautions when interacting with any online exchange service, for research I think the Lazarus group are a of group hackers who are advanced hacking techniques and abilities to evade detection, and I guess this not thier first time of trying to use cryptocurrency exchanges to launding stolen money in other to get always with the money using cryptocurrency exchanges, this is why the Government are having this feelings of calling cryptocurrency a scam.
