Wrong perception!
Do you think Bitcoin will stay at this current level when whales are trying to accumulate "as much as they can?". Seriously? Man, these whales have massive funds that could actually steer Bitcoin's price in the direction they want to.
And, do you think we're still in accumulation phase atm?
If, whales or retail investors are still accumulating, that means there are massive buying of Bitcoins, and that also means more demand of supply, and the Bitcoin value will gradually increase. That's basic economics.
I'll give you a more realistic reasons why Bitcoin is still under $10,000.
1. Because of the economic downfall.
2. Because of the pandemic.
3. Bitcoin's lack of adaption.
The list goes on, I'm just stating what suits to our situation today.
