to buy bitcoin you don't need to sell a computer if you can still use a cellphone because it's just a matter of access to buy it. People who say you can make money with a computer cannot be separated from your type of work. I mean there are people whose type of work is real outside of utilizing physical and vice versa there are types of people who work only by using a computer at home. It all depends on the type and demand of the company. a computer is just a medium that can sometimes be useless and vice versa can be very important for those who  have not gotten a great opportunity in the work at home industry but want to hone their skills by learning to type, keep a journal,  search for information on the internet, like to blog on the internet, get a job opportunity that can be done from home etc. Actually this is a relative problem depending on your interests and type.
