You are cheating with that „What else can meet those 4 criteria“ question.
The first three attributes are valid for all three cryptocurrency I have mentioned.
And as for the last one: Only one one can have the „largest market cap“ per definition of the word „largest“ which makes the question pointless.
However, „largest market cap“ is also a volatile attribute. You can lose it to the runner up at any time.
Last not least: Why are you so overly aggressive with your reply? I did not tell you or even suggest to you what to buy. This posting is not about what to buy. If you don't want to buy Ether or Litecoin: Fine.
This posting os a rebuttal of the “Bitcoin fell” scaremonger.
