The best option is to drop the money ($200-$1000) if you want no chance of being banned and getting it fast. The next option is to bot for months and just do gates nonstop. Another option is to just buy an account for a few hundred ($200-$300) and take a small risk of getting banned. If you want to play without spending then it is going to take you years to get everything you want. There are many options but to get UFE fast, you have to drop the cash or bot/buy an account. It's just how it is nowadays. It's the reason why I stopped playing the game years ago.
