Hi all,
I am new to cryptos and I have a very basic doubt(may be it is stupid)

For the tokens and coins that had ICO or funding, the value/price of the coin will be backed by the money from ICO/funding.

But how are the coins like DeepOnion which only airdrop and mine the coins get their value?

I am confused.. How will the exchanges decide their price?

Thanks for explanation, in advance..
