Blockchain.details is my preferred wallet, but the dilemma of transaction costs and delayed confirmations manufactured me adjust wallets. I am at present making use of a bitcoin wallet deal with on poloniex.com to store bitcoin
What? Really?
Why would anyone store their Bitcoins in exchanges that too with poloniex. If you day trade then it may be helpful but if you are holding Bitcoins then please get that out of poloniex and move to any safer wallets which provide you private keys.
