omg, please think about what the OP is saying, this is incredible....
yes, poloneix saw you coming a mile away, SIA started a gradual rise with a few bumps, an overall increase and they quickly hit the servers and planned the attack!
they would do the unthinkable, they would STOP you from putting a valued asset into their account! it sounds crazy, but they saw the opportunity and took it, they stopped you from giving them something of value to scam you.....
the exchanges wallet are fully in their control, if they really wanted to steal from you, they would LET YOU DEPOSIT money in their accounts! You can see they are doing it to the other member with his 6000 SIA, they won't let him have his valued asset...lol. That makes a great deal of sense, they put their revenue from the site on the line to steal his $90 investment....really?
Guess what, the exchange is probably running a daemon for every coin on there and sometimes they have problems...the traffic boost on SIA that came from the little rise and bump most likely stressed a few nodes and the wallets need a little tending, it happens...but, please...if they ever attack you again and force you to keep your money at gunpoint, let us know!
