What if I don't want to sell my keyword.

If I have a good keyword that is going to make me good money when Kooday opens. How can I keep it for me?

By raising the price. Eventually someone will try buying it. To keep it you have to afford it if it gets traded a lot.

If you want to keep em', buy em' back. The more this grows... the more the demand for the words goes up... it's getting interesting.

So only rich people will have good keywords.
If I start with a specific amount of money and manage to keep the pace buying back my keyword. Once I am out of money I will have to wait for 7 days to cash out my earnings to continue buying and at that point the price of my good keyword will have raised so much that I won't be able to buy it back.
Am I correct?

well its true the rich can only afford certain things and thats true in all walks of life

but.....

you dont need to cash out earnings to purchase keywords you can use your balance to purchase keywords

Nope, it doesn't work you cannot keep the pace unless you add funds or you let go some keywords forever.
You make 15% profit but the price is increased by another 47 % during the transaction.
So it grows too fast.
As I see it you either invest in high priced keywords , sale it and keep the profit.
Or you play with cheap keywords with the risk to keep them forever because nobody will buy them from you.
Right now it's more gambling than business.
