Hi guys...I'm totally green and I figure it is better to ask now than to not ask and make an expensive mistake.

I have purchased a bitcoin for, with fees, $2328.  I will transfer that to my Bittrex account when I get it in 4 days.  Once the price goes up to say $2528 I could sell it for a $200 profit (minus approx $7.00 fee).  Here are my questions at this point:
1.  Is a $200 profit an acceptable goal?
2.  Once I sell it how does the US dollar amount get transfered to my account?  Does it automatically get transfered into a US Dollar wallet in my account?
3.  Assuming that I now have approx $2528 in some part of my Bittrex account I could wait until Btc goes down again and then buy it and repeat the cycle (or purchase another altcoin).

Do I have it correct so far?  Any suggestions?

Thanks,
Scott
