The reason is simple, it's that he believes that this is undervalued. If he doesn't believe it's undervalued than is it worth holding?
I'm just asking about in the future would he be willing to buy some back. Of any size. If he is willing to commit to doing that in the future that is a HUGE catalyst for us all.
It doesn't really matter if Ohad thinks the project is undervalued, but rather the investors and the comunnity think so.
I suggest you read rhe entire thread to see Ohad's commitment and thoughts about the project.
There are risks in any project or investments, so I can't understand why he shall act to reduce this natural risk. Buy if you think the price is reasonable, or sale otherwise.
