No. We will go back to stable 250-275$.
This spike was caused by LTC cash-out.

Just have a look at all BTC/LTC charts.
Has nothing to do with BTC demand bought by FIAT.


The cycle was very easy:
Accumulate LTC with FIAT or BTC.
Pump LTC like shit (Ponzi in China)
Trade LTC for BTC -> increase BTC price
Sell BTC for FIAT -> drop to levels before the LTC pump

Rinse and repeat. Love that unregulated market. So many people to lose money. Thanks.
