I always said that TRON is a very speculative coin, the price can fluctuate a lot. Recently we've seen pretty big pump. I guess ETH will never grow in one day so much. But it won't fall so much as well)
Tron's community is big since they gave a lot of airdrops on some exchanges and cheap at first but its not really worth on buying Tron, if you're into day trading then buy it. In a long term, trading buy Ethereum that has so much volume and popularity worldwide and so many people uses its technology and some ICOs.
