Earlier quoted context omitted.
GP could likely do it next week if he formed a business entity (Corp, LLC, etc.), which could properly take deductions from the first dollar of expense, as (s)he described. Form the company, fund it with initial capital, then spend on rigs, utilities, & currencies. Your costs are expense-able, profits are taxable, and it all goes on a Schedule C, K, or whatever, depending on your corp type. You can probably take loss…
Unless you actually make money doing this, the IRS will consider it a hobby rather than a profession, and will not allow you any preferential tax treatment related to business expense deductions, etc. Just a heads up.
But he also pointed out that it is not required to make money from Day One, and there are other criteria. IIRC, they don't have a problem until 3+ years out, and other criteria are considered, such as following business formalities (meetings, minutes, filings), segregation of funds, accounting (&yes, filing via an accountant helps), having a storefront, business cards, website, etc. Consult a qualified accountant.
I'm also presuming the GP poster is intending to make money, so that would eliminate the issue.
