Someone has 200k of SBIT on bittrex...
be smart before thinking of buying into this
there's no safe coins , and 19% of the coins isent unusual i dont think there's a single coins without someone with 10% + of the coins atleast.
where did you get that info from ?
The new Bittrex distribution feature right here
https://beta.bittrex.com/Market/?MarketName=BTC-SBIT and it shows you the top 50 wallets on the exchange

this is a feature still in beta test on bittrex.
ALL currencies are showing a first wallet with a lot of coins.
Probably should be an exchange's wallet
Yesterday were launched two items of roadmap, including a web wallet.
Some problems appeared soon after the launch, but were resolved in a few minutes by the dev team.
Seems good to me.
