Wasn't a surprise for the most part. There were predictions before it happened and it was used as a tool by the pumpers to indicate the cap on the rise, just like they did to ETH. You do realize it "spiked" (hardly a spike with $5 increase) for no reason at all. They did it to put the rise to its place and to indicate where altcoins belong in a way.

Just like there is no reason for double bottoms, triple tops etc for a price of an asset in the crypto world. Keep in mind they may and are valid with non-crypto assets. These are just an excuse for trading activity.
