I would say that the price of filecoin is still pretty high probably too high still. Just go to coinmarketcap.com and take a look at the circulating supply and then at the fully diluted market cap. With this price that would be at more than 300B$ which means it would have a higher total market cap than Ethereum and would be the no. 2 coins out off all crypto-projects out there directly behind bitcoin.
So i would be careful to invest into filecoin now. I don't see much more room to grow personally.
