The Media would have you believe that Bitcoin is all hype:

"Bitcoin's exponential surge in the latter quarter of 2017 became one of the biggest stories of the year. However, if its current trajectory continues, it could become one of the biggest stories of 2018 for all the wrong reasons.

After starting 2017 at around $900, the cryptocurrency broke the $11,000 barrier a mere 12 hours after hitting $10,000 at the end of November before rising to a peak in excess of $18,000 shortly afterwards.

The number of Google searches for Bitcoin spiked as hype built, with volume for the week ending December 2 double that for the preceding seven-day period. Search interest peaked the week before Christmas.

However, since then it hasn't been plain sailing. A big drop in price in late December was followed by a recovery, but since the start of this year the price has fallen again.

This is a make-or-break time for Bitcoin.

In my opinion, we have a long way to go before we can call this a crash. At this point before buying most major altcoins you'll need to already have bitcoin in your possession. Something else to remember this technology is too new for us to be able to predict. Lots of assumptions need to be made. These are not stocks and we can't assume they will move the same.
