Probably the coin was a 'very good' shitcoin which was designed for this exact purpose. They draw what seems to be a good plan, launch the IEO on Binance, wait for some months then dump it drastically.
Trusting cryptocurrency project these days is hard.
Typical pump and dump schemes. I just can't believe that people still believe in this kind of things. I don't care if Binance is one of the leading exchanges in the world, at this point, all new projects are shit. Look at the price history, it looks so sketchy, getting pumped in a short amount of time. The Matic team probably saw an opportunity to make more money just like what the dev of Ethereum did to his coin.
