Five years after the relationship has ended. So for instance here that would be 5 years from the day you close your Coinbase account. In the UK the limit to sue someone in the vast majority of cases is 6 years, so I would keep anything I could need to counter a civil suit or to sue for 6 years after the fact in any case. I expect it's similar in other countries.
