Looks like there will be more round of tokens sale. First round will run through this whole October month at IDCM exchange. Need to check how much tokens are offered at first round. Also, need to check if they are going to allow US people at second round.
I can't remember reading any update that suggests multiple rounds of the STEO. Come to think of it, dreamr tokensale didn't offer any bonus to investors, so there's nothing to distinguish between the rounds for the STEO coupled with the fact that there's no allotment of tokens on the ongoing tokensales. In my opinion, the best we can get with the tokensales is an extension of the closure date and not the division into rounds.
I checked pinned messages at their telegram channel and it mentioned that round one going at IDCM exchange and will run through October month. Based on this I think there would be multiple round.
