It's all crypto currencies, not just Bitcoin. Bitcoin will survive if we see the bubble burst...it's survived 80% drops before, it'll do it again. The healthy thing about a bubble is that it cleans out the rubbish coins that have weak or no business model. It's like a forest fire, it cleans out and ultimately will rejuvenate the market.

Coins like Bitcoin, Litecoin, Ethereum, Ripple, Monero, Dash will all survive. And so will new ICOs that have sound business models. If the coin or token provides utility to the market, there will be value and growth.
