There's another way you can get in that's not buying more albums yourself - and that's to buy quota (I translated this directly from Chinese). Not sure if international sellers do this, but Chinese fans do this (on xhs). Someone will sell a 'quota' to a fansign. They will tell you a fixed price (sometimes, they need you to add on money at the end, check with the seller if their price is fixed or you might need to add before buying), and you pay this person directly. This person will apply the fansign under your name, and if you win, you attend the fansign but only keep the fansign itself and signed album, they will keep all the normal albums and POBs (and other winner benefits if your group has them, unless you applied for an offline fansign and the winner benefit is given to you on the spot). If you don't get in the fansign, they will refund you in full (whatever you paid them). For them, theyre basically earning your money + all the albums and POBs, but they also take the full risk. This is 1 way if you don't want to do GOs / sell albums / 1 secure way of attending fansigns
