I can give you some numbers and feedback (thoughts) from my Tinlake experience as a community member:
10000 DAI invested, APY ~5.5%.
- 550$ earned
- Around 400$ in ETH fee paid (onboarding and withdrawal) - which is 4%.
- Don`t forget to TAX on top of this.
Let me know please what you think will be retail investors interested to invest in Tinlake without CFG rewards and earn just 150$ (10000 $ deposit)?
Or let me rephrase the sentence:
- Would you invest in any DeFI 10000 DAI with 365 days lock for 150$ of profit+ Tax to pay?
I`m really curious to know. 
My answer is - No, i personally wouldn’t. But maybe you can provide some arguments in order to convict me to invest? That would be great.
So if we would like to cut 28% of DROP investors and focus on only Partners and institutional investors by cutting off rewards without any communication in advance (which is weird in my opinion and a lack of transparency with our Issuers and investors, IMHO) we should have a good plan how to bring more capital in Tinlake and cover all withdrawal that will proceed after removing the rewards.
