acquiring the chartered bankThey seem to have bought Northern California National Bank in Chico, CA.[1] The Column web site doesn't mention it, but they still have a physical branch in Chico.
The FDIC gives their web site as "norcalbank.com", although it does show the name change to Column. Their site has no street address and "domain name only" TLS certificate from Amazon, so you don't really know for sure that column.com is connected to a real bank.
The terms[2] are very unfavorable to the customer, especially for a business which claims to be a real bank.
"THE MAXIMUM AGGREGATE LIABILITY OF BANK AND ITS AFFILIATES, AND ITS AND THEIR LICENSORS AND SERVICE PROVIDERS, FOR ALL DAMAGES, LOSSES, AND CAUSES OF ACTION, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, WILL BE TEN U.S. DOLLARS ($10.00)."
There's an arbitration clause, and they demand to use JAMS, which is not as well thought of as the American Arbitration Association. "To reduce the time and expense of the arbitration, the arbitrator will not provide a statement of reasons for his or her award unless requested to do so by all Parties."
This is about the level of legitimacy one sees with the typical crypto operation. If you lose money through an error at their end, they don't have much of an incentive to fix the problem.
