Bitcoin is everything for me. Yes it is an investment and a big source of income for me. I get paid in my web development services using bitcoin. I also earning money by trading bitcoin to other altcoins. I all pay my bills using bitcoin.
I think the title says it all.
After a long time of thinking, reading and also investing a bit into Bitcoin I have to say that it looks for me that the main use is actually .............
Well for me maybe a big portion is for yes it is an investment coin, although im not investing any amount, just a my time and effort to earn bitcoin, and a small portion is for no it is also a currency for me. Because I could use it to pay some of my expenses as a student and as a teen. I prefer both. So yes i will consider it as an investment and as for payments.
