I want to invest good capital but dont understand why I would do this on something made out of thin air. Sometimes seems like its a lot of fanboys just wanting it to go up and up so they can then sell to retail
Don't invest any of your capital if you don't know what you are doing, BTC is not printed out of thin air like fiat, it has a fixed supply that cannot be exceeded, and once all BTC's are mined, there will be no more 'new' BTC's. This is unlike fiat that your government can decide to pump in new notes out of thin air at anytime. You are not being forced to invest, and BTC's value will go up with or without your investment, it is not like altcoins that grow just because of hype; so you are the one who needs to learn how BTC works and decide if you want to use it or not.
