2.5 million KMD @ ICO rate of 0.00012BTC = 300BTC

Did any single investor pump in 300BTC ?

Seems strange to me.

I have also tried cross referencing on kpx.io, sorted by "sent" then "descending" and nothing matches.

Only the top address matches > 2.5 million sent and consist of small 3 kmd transfers so a pool.
