Yeah, from its price you can find out how big it was, price in private sale was 5$ and now trading about 70$ in exchanges, It was something like uniswap , most of the exchanges added it and are encouraging people to invest in it and bring volume to their exchange.
This is how crypto moves, if something extraordinary happens then there will automatically be a lot of support from major exchanges to increase its credibility. Unfortunately for filecoin I missed the ICO but to buy at a price that is now around $ 70 even then it looks too high and it is likely to go down again.
