If you have seen a lot of altcoins are now depending Bitcoin or Ethereum to hold thim up because truth be told some of these new altcoins have no real back-up funding. Some of these new coins ask you to pay them with bitcoin or ether to buy them which is bad and they have no real faith in their own coins so they rely on the main coins to supply them.So if bitcoin died today at this second all of the altcoins will shut down in hours the crypto bubble will pop.
