To me, btc survival is not in question, but mining became unprofitable, so now we have many btc investors not interested in mining anymore. So, we own btc with no idea what to do with it, which reminds me on similar situation with Internet on late '90s.
Latest CHF boom also reminds us on fiat vulnerability, oil price falling also made considerable markets disturbance, gold price is questionable too - all this is supposed to influence the growth btc price but it still falls.
The planet is shaking looking for a stable financial point of support, the common people do not want to trade, but only that their earned money survive for retirement.
All above tells me that crypto currencies will survive, speaking of btc, with some reasonable btc price, most likely at $150/btc to $200/btc
