lookslike, values are already swinging between 2.2k to 4k

By the time people get on hands it would be less than half when announced, later 2nd / 3 rd batch ROI will be more than a month.

so all are again in a loop !,
Are there anybody else out there other than these Bitmain, innosilicon, baikal etc.?

As the crypto community is getting bigger, someone should start with making such asics on their own(Unlikely).
