I would like to urge everyone owning Bitcoin to verify 3 things:

1) Pls check if your bitcoin provider is well reputed, backed by top class investors and has a strong engineering team
2) Ask them how they store your bitcoin - how much is stored in hot wallet vs. cold storage
3) Do they have 2 factor authentication enabled for all accounts?
