If you were in kindergarten and you had a family member setting you up a “crypto trust” how would you want them to do it?

Let’s say you’re in kindergarten now and you have a family member that wants to create a crypto trust that you will gain access to when you’re 18.

How would you want the trust to store the crypto? Would you use hot/cold wallet or stake the crypto?

Would you want the trust creator to buy and hold crypto or buy and sell as the crypto landscape changes over the decade? If the buying and selling strategy is used how often should it be done and based on what parameters?

How would you ensure you are the only one that gains access to this trust?
