Thanks Bitshill and Xamido,

I have just checked and it is clear to me. It seems indeed that the number one wallet is Bittrex.
There are many dumpers in altcoin. I worried about the number one wallet because when XBS launched in Negeria and a large dump is coming,  money of negerian people suddenly be worth much less, this is not the best promotion would be for Bitstake to attract new people to Bitstake. (and for us investors).

but it is now clear to me.

Another question. Has Bitstake confirmed that there are already 1000 registrations (negerian people)  on Bitstake for launch in Negeria?
