I am glad to see a farmer turning into a Bitcoin investor but I believe you need to learn some fundamental aspects of BTC and the beauty of its technology which I believe is what you need to fall in love with not the chance of earning money through BTC.
Having said that, the best profit in BTC is made if hold for the long-term, not the type of investment you accumulate when dip and sell everything when it's ATH price.
For sure there is no limit to who can use or invest in Bitcoin, indeed Bitcoin is for all, and farmers are not excluded.
There Op, ensure you undergo the proper learning process to get a better understanding of Bitcoin and invest wisely because you are dealing with a volatile market, which means you may buy today, and tomorrow the market is down.
Lastly, patience is the key to achieving success with your investment in Bitcoin, don't invest and expect to get rich tomorrow, therefore buy and Hodl.
