A golden rule in the world of cryptocurrency is: “Measure twice, cut once”. Before sending funds to a wallet, make sure you have aces to the wallet. After I installed a wallet and backed up my mnemomic phrase, I always remove the account and fill in the mnemonic sentence again out of my (handwritten) back up to see or I can reopen it.
As soon as you are sure you will have aces to your wallet you could send your funds to it. Before sending the funds, make sure you filled in the address correctly, again: measure twice, cut once! I check the whole address once, and then I check the first three symbols and the last three as a second measure before hitting the “send-button”.
With steem, make sure to add the 'memo' as you send your steem or SBD to Bittrex or another exchange. Without the memo, which is linked to your exchange account, the funds will not arrive in your wallet! For steem the address is the name of the account, thus make sure to write it correct!
