There is not really a proper answer for this question right now.

Looking at the market, there was a flood of cheaper Bitcoin about 10 minutes ago, knocking down the average value around $5, to $383. This more or less resets the day's progress and thus the increase did not mean much, unless it can hit a similar value by the end of today. This is less than likely to happen, but it is possible.

For now I would argue that it is beneficial to hold onto your Bitcoin right now, and watch the market. If it gets too low for your preference, make your choice to sell or keep holding.

It's your choice, I'm not sure what the best advice is right now.
