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 ?
Popularity and manipulation has no correlation. Bitcoin is difficult to manipulate because the user base is huge. It's easier for whales to manipulate the altcoin market as it's smaller in size. To manipulate Bitcoin market, I huge amount of Bitcoin holding is needed and only corporate have such kind of money. It's rare for individual whales to have such kind of Bitcoins which will allow them to manipulate the market.
Memecoins are the easiest to manipulate. Rather majority of the memecoins are hugely manipulated to give benefits to the creators.
