You shouldn't focus only in bitcoin investments. There are other investment vehicles that can give you more profit. We need to diversify our portfolio for our future. Putting everything in one basket will make us lose everything. There's no assurance that bitcoin will skyrocket even in 2030 so better find other means for you to profit. There's still so many things and innovations that will arise every year which is maybe better than bitcoin when it comes to its performance in the market.
