I also participated in the Livetree campaign and earned 13325 stakes ($) which were converted to 22012 tokens.
Now, in their calculations, all for some reason use the current rate (1 ETH=~700$) forgetting that the same rate of ETH rose to ~1500$ and dropped to ~380$. Bitcoin is the same. Based on your logic, then you need to evaluate each purchase of tokens by investors based on the current rate of what is fundamentally wrong.
Everyone forgets that one of the main conditions for the payment of bounty awards was: "Note': Bounty is only available after the min. raise has been met which is approx. $1.5 m".
From official information: "The total raise was 1127.52868 ETH and 60.05277671 BTC."
Consider the current rate (based on your logic):
1128ETH*713$=804264$
60 BTC*8511$=510660$
510660+804264=1314500$ rounding
That is, the condition for the payment of 1.5 M is not achieved!!!
Team Livetree went to meet the participants of the bounty and paid tokens (even if not as much as we wanted); the team does not abandon the BB.

Although I do not like the rate of repurchase but I understand that it can not be lower than the price paid by investors for their tokens.
But if there are improvements for the participants of the bounty I'm IN!
IMHO
