I've been watching (and accumulating) ltc for almost a year now, I'll admit I was fooled by the false break out in April-May but I have used the last few months as an opportunity to pick up more at lower levels and improve my cost basis. The risk vs reward seems like a great play here. To me the upside potential is much greater than the downside unless you believe ltc is on the brink of existential collapse (possible but unlikely). As alway be safe, use appropriate stops, and consider all possibilities.
The chart is pretty self explanatory--the price is acting very similarly to what preceded the last bubble. Of course that in it of itself does not mean another bubble will come to fruition, but the timing and fundamentals also seem to corroborate:
Yuan devaluation (ltc market is dominated by the yuan pair unlike any other alt, an under appreciated fact)
*Hype dying down from other alts
Recent addition to GDAX
Roadmap/plans for new features added to the protocol (segwit, confidential transactions, possibly smart contracts)
New found appreciation for scarce, immutable, thermodynamically secured (POW based) blockchains
Also, in terms of the technical picture, LTC/CNY is very close to clearing both its 100 and 200 Day MA’s, where as btc is already well above them. If and when it does--the momentum should pick up. Interestingly enough, both LTC/CNY and BTC/CNY are each setting up for their 50's to crossover their 100's, but for LTC/CNY there's also a Golden Cross (with the 200 day MA) in the works.
*Eth has stolen the spotlight and liquidity from ltc over the last year, but now it would appear the hype has died down after all of the ongoing crises's (DAO collapse, Bailout, HF/ETC, ongoing DDOS attacks, now another dual hard fork on the way, blah blah). ETC had its big bubble, but has yet to reflate (has to do it's own HF as well). The privacy coin play got a huge bump with XMR and its adoption in a big dark market, but now that bubble has popped. Zcash still on the way, worth keeping an eye on, but still many questions remain about it. Haven’t followed Ripple much but I know it had a big bump in recent months that died down as well.
