I'm just curious, are they just the same?
Not really. but there are some coins that works that way such as ICONOMI. those coins that supplies are limited especially to 100M only such as wavesplatform.
stocks can be risky if you don't have inside information to companies you invest with.
I never heard that iconomi was limited supplies.. so they will never generate new coins in the future and it will stay at that amount?
Unlike bitcoin that always farming bitcoins or mining to generate bitcoins that we can use.
Did you really miss something,even bitcoin is limited and so is the reason for the price to grow like this .Iconomi is an asset based on the Ethereum platform while bitcoin is a currency which is really used in transactions and other uses.while i doubt the same is used in Iconomi or the project is still under development.
