I wasn't buying Litecoin at $10, or $7, and I'm not buying it at $4. Trying to catch a falling knife is unlikely to be successful.
I wouldn't even pay $1 for it - it's a FORK of BTC with almost no merchant coverage and it arguably is abandoned when we consider Charlie Lee left full time development to pursue a salaried job at Coinbase.
Haven't bought any BitsharesX either - everyone knows that BitsharesX volume was almost entirely in China and by private funds / ponzi scheme investors.
