I can think of four reasons:
- Mixtum & Mixermoney & WebMixer& jambler was paying about +15K per week, so the forum is important to them, especially after CM was banned.
- ALTT is still small compared to BTT.
- If any legal problems occur, then jambler will be safe as the actual mixing is done through partners.
- From a technical standpoint, modifying the code is easy. Instead of calling ----> https://api.jambler.io/, they can copy the content of the code to partners back-end and call Liquidity lib code. Conversely, it will be an advantage as the mixing algorithm will be unique for each partners.
They don't necessarily announce that the upgrade is due to BTT but to make their system more "decentralized."
