Another update:
I have just paid out travel and accommodation reimbursement costs to Michael, Annemieke and Ryan for a total of 3571.70 USD. (Some luggage costs still pending)
The budgeted amount was 5400 USD so already 1800 USD saved.
3571.70 USD was bought for 36131 BTS from the worker's balance (avg price 0.0989 USD/BTS)
Total spent so far = 252575 BTS
Worker total funding = 369250 BTS
Remaining worker balance is now: 116675 BTS
