Moved to Saigon from the Bay Area about 2 years ago. Was unemployed at the time (I mostly do tech consulting) and sitting in the newly opened cafe in my apartment building. A guy sits down next to me and is reading a book about bitcoin. He just moved into the building a couple days before. We start talking and he tells me he is mining, invites me to come help install the next shipment arriving that weekend. I go with him to the data center located about an hour outside Saigon, which turns out to be in a super secure Vietnamese military telco building and install 150 new machines. Had a blast doing the install and I got a job offer to become CTO to help run the operation. 8 months later, the whole operation moves to Canada and I'm out of a job again (long story). Telling the story to a friend of mine, he offers me a job working for another large crypto company that he recently joined, to do an even larger mining operation. So here I am... working on that now.

Needless to say, I'm a huge believer in serendipity.
