Of course I really want to do that but it's really difficult to find out an offline business accept Bitcoin cause Bitcoin is not really well known like everyone still thinking. Beside Bitcoin is not legalized worldwide so in almost country all over the world people can't use Bitcoin to invest in offline business and my country is not an exception.
Yes thats true, one cannot find an offline business where Bitcoin is being accepted, and you cant invest your bitcoin into offline business, because Bitcoin doesnt have a physical form so it can only be used online. If I want to invest my Bitcoin into an offline business, what I will do is sell it and convert to cash, which I will then use to invest into a business like farming preferably. I believe farming is the best offline business one can invest into and make huge profit.
It is all about investing your bitcoin offline and you can definitely withdraw in fiats and invest in something you may have passion for.
For example, after I was able to have enough bitcoin and the value has increased, I took out some in fiat and invested in some few offline businesses related to commerce and I have been making so much and also buying bitcoin back. Looking to integrate bitcoin payment in my store very soon.
