Thats really negative thought and I already don't like it into your heading! Bitcoin will reach that mark in the future for sure, no one can predict when but it will reach surely. There were lots of whales in previous time also who used to do the same thing, hold and take the profits from 5-10% hikes. The swing trades are anyway common anywhere but they are not risked by whales at all. There holdings are enough for them to get started and grab the profits (huge one) even if the bitcoin moves little bit upwards. I think whales are the smartest people who wants bitcoin to spike to 20K and I think they are not the opposite one.
