Take a quick look at the current market situation:    

What does it look like to the newbie in crypto? Lets review this little quick:

BTC is going up in value, while almost all other coins are in the red zone. This means that it is doing well and is a good investment at the moment, right? Maybe we are not too late to invest in it and the rumours of its price to rise up to 20K and even 100K may be true.  

XRP is going up in the last 24 hours, seemingly following BTC, which must mean that investors are getting more confident in it. Hmmm lets buy some XRP.   

The other coins are down, thank god I did not buy into Cardano or Polkadot. I knew they were not the real deal.  

What they dont want you to know:

BTC is being pumped artificially, with the media around it and all these big companies investing in it, making people believe it is a hedge against rising inflation caused by the overworked printers of the FEDs money printers. Somebody(s) wants you to buy BTC at this price, and has been doing so since BTC went up from 9K or even lower than that. PayPal News of crypto adoption, BTC maximalists influencing people to buy into BTC and every other news you hear on the mainstream media (if you are lucky enough to go past the COVID News), make it seem very reasonable for the price to go up, right? 

Ending thoughts: 

The crypto market, like the stock market is driven not by reason, but by greed. Greed is what makes the billionaire, which has 10 billion $, to have 50 billion $ or 100B $. What else? What can he not afford with 10 billion $, so that he needs to have a few extra billions? And who manipulates the markets except those rich people aka Whales (or their bots) that can sink or rise the price of the whole market with their sell or buy orders?
