yesterday, I withdraw 0.16 monero from bittrex to

https://mymonero.com/#/overview

it's show transaction and balance properly

then I deposit more 4.07 to mymonero.com

in bittrex, it work properly

but nothing happen in mymonero.com

many hours ago, I log in mymonero.com again

and it's show 4.23xmr in mymonero.com properly

but today I log in again

but 4.07 is gone

0.16 still balance and transaction history is still there

but not for 4.07

then, I just tried to withdraw 0.05 to bittrex and it show transaction properly

but 4.07 xmr still unavialable

I wait for sync until the wallet log out it self many time

4.07xmr still invisible

what should I do?

why this wallet is so unstable

and problem happen only for large amount

but now, I just tried to import the wallet key to GUI

It's show 4xmr

but when I tried to send xmr to bittrex

"send" button is unavialable

why?

but from this case make me change my mind
