It is not a good ideal to inv all momney into btc, because it can be bad if you are making mistakes with Bitcoin so you can lose also a lot of money if you selling it too early.
In my opinion isnt a good idea invest all your money in only one thing. You can be a millionaire in some years or you can be a broke guy in some hours.
Exactly you cannot afford to trust bitcoin so blindly that you put all your money into it, as if bitcoin disappears in future then it will surely wreck your life.
