When HODL'ers say "HODL HODL" they are either lying while they are selling. Or if you are truly HODL'ing then you simply being scammed by the other other HODL'ers who are busy selling to you.....
I'm an HODLER and keep on holding though I'm saying those words I literally do it. I don't have a way to manipulate the market by just saying those words, I decided to focus on long term hodling so it doesn't matter to me if they are selling.
Those whales are just watching the market and happy to see people panic of selling like the way they do. This has been the situation mostly for inexperienced holders, when they see a quick dump, they don't know what to do but it urge them to sell immediately.
