This invite link doesn't work
The code in the link doesn't exist or is no longer active. Ask the person who sent it, or just try Tách Nhạc: it splits the vocals and the instrumental out of a song, with free runs and no code needed.
You can earn 50% cash by inviting friends too
Every account has its own invite code. Every time a friend you invited tops up, you get 50% of it in cash, for 1 year.
