The crypto is the wealth
I think it depends on how much you want to cash out. If its a large amount, make sure to discuss it with a lawyer and an accountant to see what you need to do to minimize taxes.
There are service providers that will allow you to get a loan against your crypto which is not taxable (at least in the US). Check out Salt Lending if you are interested in this approach.
You can also look into doing a private placement type transaction. Check out IBC (International Blockchain Consulting) which offers an OTC Dark Pool for high net worth people where they help people buy and sell large amounts of crypto.
I would be careful about using family or other 3rd parties since it could be considered money laundering if you intentionally structure the transactions to avoid reporting the transactions. If you are in a corrupt country, they will be more than happy to throw the book at you, send you to prison and steal your crypto so please be careful doing this.
I would highly recommend speaking with a competent attorney and accountant when selling large amounts of crypto.
