Pergi ke halaman pengumuman Binance untuk melihat dua kali terakhir, dengan format khusus untuk Binance akan merilis CLOAK, MOD, SALT, SUB, WINGS, CHAT, ICN, TRIG.
Reptilia akan menggunakan kata kunci yang sama untuk merayapi pengumuman pengumuman baru, tentu saja tidak mengesampingkan perubahan format pengumuman yang dapat diperbaiki. Karena tugas reptilia terlalu sederhana, akan ditulis dengan JavaScript sederhana. Setelah merayapi koin, akan memeriksa informasi akun, jika ada koin, akan menjual semuanya dengan harga yang lebih rendah, jika ada pesanan yang belum selesai, membatalkan terlebih dahulu. Sampai koin yang dimiliki benar-benar terjual. Di sini ada beberapa artikel yang membahas tentang blog ini.https://zhuanlan.zhihu.com/p/57012933
