What are the disadvantages of DOTS?

I've heard so much buzz around DOTS in the cryptocurrency and finance space, but as an investor, I always want to understand both sides of the coin. Could you elaborate on the potential disadvantages of DOTS? Are there any specific challenges it faces, either technologically, economically, or regulatory wise? Also, I'm curious about its scalability and sustainability. Do you see any red flags that might hinder its long-term growth? It's important for me to make informed decisions, so your insights would be greatly appreciated.
