I'm new to Tezos. I don't understand this phrase:
The rub for investors is that generally speaking, validators running proof-of-stake nodes (known as “bakers” on Tezos) must have some funds online and so effectively “hot,” in crypto security parlance. That means these funds are more vulnerable to theft than when the private keys controlling them are kept offline, in so-called cold storage.
How is it unsafe for me to delegate? I own my tokens.
