Which ways exist to triple your money in one year?

[Ludanto]

Let's say you want to triple your money every year.
Let's say you start with 1 dollar. After one year you want to have 3 dollars, after 2 years 9 dollars, after 3 years 27 dollars and so on.
Let's say you have 12 months in which you can spend time to learn anything that you need to accumulate money in some kind of way. (But you are allowed to learn only one 'craft'.)
Which craft would you choose to learn and apply?

I know that you could triple your bankroll yearly for some years with poker.

But what other possibilities are out there to triple your money each year and how risky is each of them? What is the safest way to triple your money each year?

I know of sport betting, investing in stocks, trading, manufacturing something. What else is there? What is the most sure way of trippling your money each year if you really do your best?


Somthing tells me that earning money and increasing your wealth exponentially in this world is easier and can go faster than many people might believe if you know what you are doing and if you are serious and disciplined about what you are doing. Also thinking long term seems crucial.

Am I just dreaming?
