Usually litecoin is lot more stable than any other coins. But in couple of days LTC has grown dramatically too high. What could be the possible reason behind it? Is it too high to invest in LTC now ?
1) Very low transfer fees mean it's being used as a currency for cross-exchange transfers.
2) Founder Charlie Lee has been on TV a lot
3) Coinbase/GDAX only offers BTC, ETH, and LTC. Coinbase is the primary fiat ramp for American investors, so they have to choose one of the three and LTC looks "Cheapest" to new investors.
4) It does everything bitcoin does, only 4X faster and two to three orders of magnitude cheaper.
5) Hype, momentum, and the madness of crowds.
