Just found this BTC calculator https://dcabtc.com/ How do you invest in Bitcoin?

Hello Gang! My name is Drew. I’m a full time Fire Engineer Paramedic. Husband and father of twin toddlers with a 3rd kiddo on the way. Happy to be alive. We have a small homestead, chickens, pigs and about 30 fruit trees. All free range organic. My wife and I are interested in health, freedom, sovereignty, raising our family, and I have been learning more about investing over the last 4 years with a huge interest in Bitcoin. We are mainly focusing on tapping into my network at work, selling eggs, meat and fruit to guys at my fire house and eventually to more. I have been following and paying for educational content on macro economics and investing and feel that this knowledge is key to developing a life of freedom. How do I leverage this experience into a business venture? I really want to build up the 500 members of my fire department because we have so many new members that are young and could really benefit from some one sitting them down and talking to them before they get wrapped up in their lives and careers. Plus this is really the only edge I feel I have at the moment. I’ve earned a good reputation as a firefighter and want to extend to my learning in other aspects to my fire family. Any advice is appreciated!

For the serial entrepreneurs of the group, what have you found to be the easiest way to access capital to buy a business that is for sale by someone retiring? Do you try creative financing?
