Bitcoin is popular among huge population all over the world while the demand for altcoins is limited. Does this mean there is least effect of whale manipulation on bitcoin among all crypto coins ?
The demand for altcoins is limited because their name is pretty self explanatory: alternative coins. Alternative to what? To bitcoin. If you really believe in cryptocurrencies bitcoin is the clear choice, is you want to take some risks then buy altcoins. Manipulating the bitcoin market is way more difficult today compared to years ago but, in my opinion, there still is manipulation.
Considering it's market cap and the numbers of investors involved, whales manipulation might be a difficult thing to say when it comes to Bitcoin. But we can't overlook the effect of news and rumors. Bitcoin just went below $54K some minutes ago, with no clear information on what happened or who is selling. This is a clear opportunity for few individuals(not sure of who they are) to start passing rumors inorder to push others into selling, so they can buy the dip for themselves.
