1. Too new - just a few hundred billion - grain sand in the desert - lucrative market of sharks because they also manipulated.
none of your reasons make any sense! as @stompix said above, being new has nothing to do with whether or not they are going to fail. and what the hell does grain of sand and few hundred billion has to do with anything here?
2. From 1 inferred capitalization now nearly 400 billion. Bitcoin accounted for 35.6%. That means 140 billion. Someone e predicted 5000, we just do a simple math. If btc is 5000 then the market cap will lose 40% = "bitcoin to 80 billion - the total market is 240 billion .... If this number really happened, I would say at least 70-80% of the new investors running long because the milestone is 5000 / milestone within 4 months of the crypto ... who dare to put money into a game too risky??? If it was me, then I would not. Sharks also understand that, and they do not have the money to spare and lose their prey. Squeezed 5000 do not know 20,000 BTC enough not.
this is your worst one among the three! you are using a meaningless attribute and then play around with numbers! market cap means absolutely nothing. and you know what i am going to put it like this for you: saying market cap is X so it is big and bitcoin has Y% of it is like saying the cryptocurrency market weights 238 Kilo Grams and bitcoin smells like daisies. and i am not making a joke, using weight and smell for a cryptocurrency is the same as using market capitalization for it.
3. Blockchain applications increasingly show strength and potential. Technology will not die unless people want to go back to prehistory.
not really.
there are a some ideas that seem cool and there are shitloads of pretty advertisement for a lot of them mostly to get more money in their ICO or get a nice pump for their coin. i have not seen any actual application among any of the altcoins!
