Based on the existing answers and question, it appears that the person is interested in buying a large amount of Tez (XTZ) tomorrow. While it may be tempting to buy a large amount of Tez in one transaction, it is often more beneficial to accumulate Tez by holding fiat. This allows you to spread out your risk and potentially benefit from market fluctuations. Additionally, by holding fiat, you can take advantage of any dips in the market to buy more Tez at a lower price. Ultimately, it is up to the individual to decide the best approach for their situation, but accumulating Tez by holding fiat is often the most prudent option.
