The crypto market is born for organizations to manipulate money. We call them whales and certainly the price of altcoins is unpredictable in the future. Because people with money will often control the market and we cannot do anything else.
And one more thing is that the SEC also cannot control our crypto market and manipulation will never stop.
Cryptocurrency technology was never created specially for the whales to manipulate the market, they simply just saw one of the lapses of the system and decided to take advantage of it. Satoshi created it for peer to peer transactions, so that everyone can have full control over their financial transaction without any blockage to it.
People investing large sum of money is natural in every market, both stock and forex market, you need to research to see how much people are moving through these markets too, but because they are both regulated, it become quite difficult for it to be manipulated like crypto, therefore the call for regulation is very necessary.
