Don't be naive, it's time to wake up! Pawnshops will not accept such high-risk things. Digital products are the least valuable. If you want to transfer MP4, you have to go to the flea (second-hand) market, or publish the transfer information in newspapers, radio and television, or go to Jiji.com and 58 Tongcheng.com to publish the transfer information. This is the most correct choice! Even the brand-new unopened MP4 is basically transferred at half price. If it is old, even if it is only inferior in appearance, it can only be sold at a fraction of the original price. If you feel bad, keep it for yourself. Besides, high-end smart phones are very popular now, and all the functions of MP4 can be achieved. They can also call the Internet, partly replacing tablets and partly replacing digital cameras. And MP4 can't surf the Internet. In this era when everything wants to be integrated and one thing is multi-purpose, most people will not add another MP4 just to watch MP4 movies. This is the reality! You can go to the computer city. Even Android tablets may not sell well. More people change their mobile phones frequently. This is the general trend! Pawnshops basically collect valuables such as gold, jewelry, jade, antiques, celebrity paintings and calligraphy. And they won't be stupid enough to accept such ultra-fast and precarious electronic products. Bosses are all skilled people, so you are the boss. I hope I can make a profit without losing money. Do you think I'm right? Thank you for your question. I wish you peace, health and good luck!
