Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

What are some realistic ways to earn 10 cr in 20 years?

 Earning 10 cr in 20 years is a significant goal, and it will likely require a combination of consistent effort and smart investing. Some potential ways to achieve this goal include:

Investing in the stock market, using the principle of compound interest to grow your money over time. For example, if you invest 10 cr and earn an average return of 10% per year, your money will double in about seven years.

Starting a small business or side hustle, and using the profits to invest in growth and expansion. For example, you could start a lawn care business with just a few hundred cr, and use the profits to invest in more equipment and hire additional workers.

Participating in a savings or investment plan that offers matching funds from your employer. For example, if you contribute 10 cr per year to a 401(k) plan and your employer matches your contributions dollar for dollar, your money will grow even faster.

It's important to note that these strategies will not guarantee success, and there are no guarantees when it comes to investing. It's always a good idea to do your research and consult with a financial advisor before making any major financial decisions.
