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 ?
As for Altcoins, I don't think it's impossible for marketcap manipulation to occur, but with Bitcoin I haven't found a strong reason that can confirm that Bitcoin can be manipulated. The repeated sentence is not none, but a little.
You can do the rest yourself. The level of difficulty whales have in manipulating the altcoin market is different when they try to do it on the Bitcoin market.
Altcoin marketcap who is willing to pay more.
