What if you are in need of money so badly? Making loan on banks will surely take up time and the last resort wold borrowing on your family members.
Yes that is a fact that taking loan can take more that a week, therefore it is not a good option, to me I think bitcoin is the best option, as for me I can sell my bitcoin within seconds and can widthraw my money in form of fiat currency within 3 to 4 hours, therefore I think if you are in desperate need for money still bitcoin can help you providing you money urgently.
