If I had to choose, to reinvest is a good option. Promotion is going up since launch of affiliate program and in weekend there are less investments. I think 101 hours more should be profitable for you, and even you can reinvest again.

But everybody should choose the best moment to reinvest, this means when your current balance + you shares makes a big deal. To wait until last hours of expiration of an investments is not the best option.
