Guys I dont know what to do, should I invest in Gold or Bitcoin. Gold is more stable I know. But the bitcoin development is crazyy, imagine if you have bought it before 20 years... 
If bitcoin was able to make a lot of progress within 10 or 20 years, then how much more in the next possible years to come. Do not just do the computation, but make a final move. While bitcoin is a good and safe haven investment, bitcoin is more than that. You'll definitely become extremely rich if you know how to make advantage every opportunity that comes. I guess you wanted to say that "gold" is a good & safe investment, but Bitcoin is more than that. A little mistake... I agree with you completely here, bitcoin is a lot more than just investment, and I still believe that bitcoin can be a game changer that this world needs.
If someone is hesitating between bitcoin and gold then they should invest in both... as you wrote, gold is a safer option and there is no mistake with gold. The price of gold will never stop rising, slowly but surely the money invested in gold will retain and probably gain in value. But Bitcoin has much more potential for growth, and I think it is certain that Bitcoin will continue to break records in the future.
