Some friends told me that I could join a few PTCs
to make money.But I don't have my computer so I can't do the job everyday.
The most difficult problem to me is having no PC,can I also make money?
A personal computer is not the problem but the solution to your problem. Therefore, what you need to do is find ways and means to buy a PC. As the saying goes, "If there's a will, there's a way."
