What exactly do you mean by agriculture development? Like as in, developing the land you just said and making it grow using crypto? Or is it a research-based agricultural development that you would want to obtain? Either way, crypto isn't going to help you. I mean, both endeavors require money, yes, but using fiat or crypto doesn't make any difference. What makes a difference is the talent you have in managing/researching the so-called "development" you would want to have.
Crypto isn't some magical seed you can plant and it grows a beanstalk that has technology far advanced than the current civilization, it's just fiat. A mode of payment for transactions BUT is unregulated by the government. Thats it.
