No coin or token in existence is worth 0. How much its worth depend on collaborated effort.

The Flatland Masterpiece form 1880 springs to mind
https://www.goodreads.com/book/show/433567.Flatland

Extremely rarely because lack of volume makes it hard.

The future can only be free of any 3rd party's involvement.
We had segregated witnesses for the past hundreds of years.

On Septemper 1  the marketcap was

Bitcoin     $ 2,693,687,596
Ethereum   $ 554,484,635
Ripple        $ 327,243,422
Litecoin      $ 252,960,022
Etherum C $ 53,581,348
Monero      $ 50,336,321
Dash          $ 23,168,271
Nem          $ 16,826,997
Dogecoin $ 111,679,987
Namecoin  $ 8,648,046

All sorted to full satisfaction

On average, for the past 3 months $20,821 USD was invested in Dogecoin every single day.
For reverence NEM managed $34,892 per day and Namecoin just over 5k.
In the same timeframe R3 Hondco LLC bought 198,448,248 million xrp at $0.0085 USD each which averages to $18742 a day. How many they managed to resell at $0.2 is anyones guess. (if all would be $444,444)
When a new dev is found, one would expect a nice price rise.
A total of $111,679,987 USD is invested in Dogecoin so far. Not going to disappear in a hurry, i guess.
Will thousands of other coins have a future?


 

In crypto Marketcap is extremly poor indicator, almost useless.
A better way to judge is how many coins at what price sold on average for the past month or so. Also Volume is important.

There is no mystery to it. For example Bitcoin mined    152 Blocks last 24h each one is 12.5 BTC, makes it 1900 new coins last 24h.
Miners must recoup investments and running expenses. So more or less $8,934,226.6 USD of new money has been found to pay miners and everything else associated with generating a new coin.

Dogecoin is a good example, in the early crazy days miners reward was huge and so was price thats why a total of $112,450,599 was paid to miners, but only $24,858 for the past month on average per day.

Monero paid a total  of $60,620,373 to miners (which requires new money) and on average $338,447 daily in August. (last 24h 712 Blocks, 6.54 XMR for each block)

So how much money is actually invested in a coin on a daily basis. Marketcap does not show it it just shows if existing coins traded higher or lower not how much new capital was injected.

Ripple
The total is established by how many coins sold at what price. The total is the highest as most sales would have been in bulk lots. Correct numbers gives sales tax records.

Dash
Only the miners reward from 80% down to current 45% is added as it is the only new investment. Masternodes is just the same re-invest, re-invest.........

Nem
Supernodes reward is added as it more or less does the same thing than bitcoin miners by giving the chain security. The coins exist, but are reserved. About 700 supernodes exist. Technically all could be one entity.

Dogecoin
With the high reward and high price at beginning the total miners received is high, but new money flowing in is low.

IOTA
Not considered because the controlling super note is closed source.

Price is important?
In such case 42 coin is one of the best if not the best at over $8000 a piece.

At the moment Bitcoin Cash has a lot of catching up to do.
$6,000,000 Million invested in Ethereum daily vs  $500,000 Thousand in Bitcoin Cash

It is a long way of.
Ethereum has over 6 Million invest daily, Bitcoin Cash so far only had once more than 400k a day

After two weeks a total of $1,312,185 has been invested in Bitcoin Cash and $86,036,259 in Bitcoin brings the total to $2,779,723,855

Satoshi could instantly deceit which is his chain.

At the beginning Hashrate distribution does not look good.

Because Dogecoin and Namecoin are merge mined, security is sorted so as long as Bitcoin and Litecoin exist nothing can happen to Doge,Namecoin. At the moment $ 25,000 is invested in Doge every day.

Thanks for the heads up, but a little more info would be nice.
But then again would not be surprised Dimwit being a scam.

500 gigabits

Depends which Bitcoin alternative over 90% will fall on the wayside.
Once upon a time Terracoin, Peercoin (revolutionary first pos), Worldcoin, CHNCoin, Auroracoin............ where top coins, modern top coins are no different.
With everything and anything, what is it backed by?
