Be sure to stay safe when attending in-person conferences. The most expensive ticket to TOKEN2049 this week: $4 million.

Trader Frogman @frogmanhaha was attending a conference in Singapore. At 4:30 a.m., while he was asleep, two of his wallets were drained. The funds were laundered through privacy tools and cross-chain bridges.

It’s still unclear how the theft happened.

If you’re traveling for a conference, consider leaving your main wallet and everyday phone at home and taking only a backup phone.
