I am almost 100 percent sure that the market is controlled by major players. Their names you and I don't expect see. There are large corporations that want to take over most of the mining system and therefore displace other smaller corporations.
I don't think so because in my perception nobody controls the market of crypto Its depend in our experienced in trading and how lucky we're as well. Sometimes i do trade crypto in my vacant time and I look for an altcoins has a big volume and very fluctuated. In that scenario i play its market by doing quick buy and sell until Ive earn profits enough for myself.
