@Daniel what @Abu2017 says is that is not important the supply of ADA or BTC, what’s important is the supply of the smallest unit that a currency have:
BTC smallest unit = 1 BTC / 100,000,000
ADA smallest unit = 1 ADA / 100,000
this gives different maximum supplies than the one commonly thought:
BTC max supply = 21,000,000 * 100,000,000 = 2,100,000,000,000,000
ADA max supply = 45,000,000,000 * 100,000 = 4,500,000,000,000,000
so ADA has a maximum supply of just above double what bitcoin has.
current BTC market cap = $230,000,000,000
Satoshi value is = $230,000,000,000 / 2,100,000,000,000,000 = $0.000109
current ADA market cap = $10,000,000,000
Lovelace value is = $10,000,000,000 / 4,500,000,000,000,000 = $0.000002
what if ADA were to get bitcoin shares of the market? shall we add Ethereum shares too? yes why not…
hypotetic ADA market cap = $230,000,000,000 + $64,000,000,000
= $294,000,000,000
Lovelace value is = $294,000,000,000/4,500,000,000,000,000 = $0.000065
which means: 1 ADA = $65
as @mkultra says it doesn’t really matter, it all depends on how people give value to things. but at the same time what @Abu2017 posed is a very interesting topic.
if we say that all the value in the world is represented only from ADAs I think that what counts is the number of smallest fraction you can have that count, not the arbitrarily chosen value of smallest bits that someone chose the arbitrarily whole bit must have.
If it is a database what counts is the number of rows I can enter that will give me the amount of information that is possible to store, not the whatever underlying hierarchy.
or put it in another way if I have a CD-rom with 600MB doesn matter if I call my CD-rom “0.6_GigaByte” or “6-centurion-MB” it will still hold only a low quality moovie and one bit will always only represent a 1 pixel so to speak.
