CryoBit

No. CryoBit manufactures physical objects — metal cards and coins — that let users store private keys completely offline. It never holds client funds, maintains no online wallets, and has no ongoing relationship with the buyer after the product ships. The user retains full custody and bears full responsibility for the physical item.

CryoBit's own website explicitly names bitcoin and litecoin as the supported assets. A limited-edition product was also made for BlackCoin. The products work by physically storing private keys, so any asset whose key can be encoded offline could theoretically be stored, but the firm's marketing focuses on those two.

The co-founders are two engineers who have been friends since college and crypto-currency enthusiasts since 2011. They have chosen to remain publicly unnamed. The business is structured as a Florida LLC, and all public-facing contact goes through a generic support email and a toll-free phone number.

CryoBit was created specifically because a paper wallet was destroyed by an apartment flood. Its products are designed to resist water, humidity, fire, physical impact, and corrosion — the primary threats that make paper wallets fragile. The metal construction is the core physical differentiator from a simple printout.

There is no public evidence that CryoBit operates as an investment firm, makes fund commitments, or holds crypto on its own balance sheet for investment purposes. It appears purely as a manufacturer and retailer of physical security products for self-custody.
