Very often it is just a huge whale selling his stake for fresh bitcoins when the hype is high. During this time a lot more buy support. He can then after put the price back at the same old level with only 25% of the btc he just cashed. Another 50% he uses to pump the price higher them before. The other 25% is breakeven from what he bought initially. Over the next month we will see this pattern evolve.
Moreover I saw this whale when price was at 27k he ate everything till 24k with a 50 BTC wall
I'm 90% sure it wasn't the whale eating those dumps but was doing the dumping himself. That 50btc buy wall was more likely a bull trap to have ppl buy his remaining sell orders before it dumped way down which it did. This isn't to say that eventually amp will rebound in the future.
