The Binance direct fault and whales manipulation theory is sounds like fiction to me. As we all know that "Matic Network" is just a new project and because of that reality, I strongly believe that the "caused" of that price fall is just an ordinary dump from its investors who "unsure" of the market outcome in 2020 or maybe those investors is just after for the profit. Because i believe that more and more investors nowadays has already learned in its experiences in 2018. if i am an investors and i see the market was continue to decline like these time i will do the same to secure my investment and earn some profit out of it to avoid losses.
