Frustrated my 1000$ Worth of Bitcoin to SBD Disappeared??

So I have been researching, commenting , upvoting and trying to invest in steemit so I can get the biggest rewards and success on steem.

I was able to get initial 250$. I tried to add another 1000, Coinbase says it was sent for 24hours never showed up on in my Steemit wallet.

Just check my coinbase account and it is like the transaction never took placed. So frustrating. So much time wasted. Also BTC now down 1000$ since I did this. Arggggggggg. Can someone please help me and explain why this happened? I would love to have just one thing take only one time and not waste so much of my time and money . Thanks for you help.
