Phoebe, who files single, holds several crypto wallets with large account balances. Her adjusted gross income (AGI) is expected to be around $475,000. If she decides to sell off some holdings, which of the following techniques can she use to lessen her tax impact?

1. Since the market always rises, she can sell first-in, first-out and will always be selling the lowest basis coins first.
2. If she reinvests her proceeds in a Qualified Opportunity Fund within 180 days, she may defer paying any tax on her gains. This will enable her to spread the tax impact over several years.
3. By selling her short-term holdings, she will avoid capital gains, and she can pay ordinary income rates on the gains
4. Each wallet is treated as a separate business entity. She can sell a little from each and it won't impact her taxes at all
