Has the crypto industry developed any type of solution for such transactions?
Crypto auctions, algorithmic trading and over-the-counter (OTC) desks are designed to transfer large amounts of crypto.
In cases when you want to trade your crypto assets directly, without splitting them into parts and calculating fees, the daily auction held by Gemini — a U.S.-based, regulated crypto exchange — is a popular way to do that. Orders are currently available for five major currencies — Bitcoin, Ether, Zcash, Litecoin and Bitcoin Cash.
