Bougth CBX on Banx.io, no problem and withdrawal to my wallet was OK.
I dont trust YoBit because many wallets are in maintenance (less than craptsy and more than c-cex i think, yobit suck with that too) and because they encourage and help scam ico.
Then i tried to send 1 CBX on two others exchange.
Both are confirmed but are "not yet redemed"
Sended from my wallet 1 CBX to Cryptopia, oups there wallet say "waiting for update"
( my fault, have'nt view the icon before i sent, np i will get them once they update the wallet or know their is an update )
Sended from my wallet 1 CBX to YoBit, ...
I looked before their wallet and was ok: Wallet status: Online (1317253 blocks)
But one hour after and more than 37 confirmations, nothing received and nothing on incoming deposit

while i get them in few seconds with banx.io
If i cant deposit 1 on Yobit, i will not place a trade to buy then. (same for cryptopia)
My wallet is in 2.3.0.
