No, this is a guy who desprately needs money or wants the price down even if it costs a BTC or so.
I think so. Maybe the dutch bancing sector has hired someone to do this

But what a stupid way to act like this.Can't go on for ever, then he is sold out

The coin has been range bound for a month at this level, something had to give and it ended up being the sellers being impatient. The buyers are standing on the sidelines, remember that 1 btc sell wall that got eaten up a week ago at about 153-154, the buyers waited until it was low enough before taking it out.
There is a lot of btc and NLG that is waiting and ready to snipe out good deals.
