Are you asking if you were to sell today you would be able to find buyers for 333 BTC  ($5K worth at $15)?

If so, yes, ... the market can absorb that all at once, and you would get just over $10K ... calculated using 333 BTC X $30.50 X .994 (assuming a 0.6% exchange fee).

Thus yes, that would allow you to sell it all today and double your investment.
