All the currency may perform differently depending which time frame you take into consideration. As long as I'm recording this data Litecoin showed quite increase, although I wouldn't say it's the biggest gainer. On the other hand, you never know when those "biggest performers" would drop down.

Just one of my experiences...
About 2 years ago I won some lottery or something with 168 LTC. At that time LTC was worth around $4 or even less. Of course, I needed that money and I withdrawed it. Only a small portion I left to invest in something else.
Just a few months later it jumped to about $70 or $80. Do I have to tell you how stupid I felt??? 😉🙂 Not to mention this past mid of December when it was over $300 (before it dropped to the current rate).
But there is no use of crying over own faith and stupidity as from current perspective it's all just a long ago spilled milk. At least I think, I learned something from that.

And that's why I don't want to even bother myself with Steem ups and downs. For now, I'm just trying to collect them as much as I can! Maybe I'll change my mind tomorrow, but today it is as it is. 😉🙂
