Guys First do not judge me because I am a Full Member.
I just want to ask if you get to ask to provide ethereum wallet. What is the wallet you give and use? is this poloniex.com one of them?
Do not use poloniex to store your ethereum because polo will not give you the private key for your address and some users having problems withdrawing their coins in polo. If you want to store big amount of ethereum I suggest you to buy hardware wallet (Ledger Nano S or Trezor) or you can use the official ethereum wallet (Mist) and install it on your desktop. Jaxx and Mew also one of the best.
