Some of my layman's opinion would be that the e-mail was written by the same people who were behind the project with the reason that they would scare you into continuing with what you are about to do.
The email came from what appears to be a real lawyer.
Btw is it against my interest to publish selected identifying information here? For example the email and website of said lawyer.
I can't think of a valid reason where this can be used against me.
However, the message also mentions some interesting things like :
Please be reminded that your purchase of tokens was a high-risk investment (as you can double-check in the “Real Crowd-Sale Agreement” you executed with Real Estate Asset Ledger Pte. Ltd on the 31st August 2017, and its exhibits, particularly, Exhibit C), undertaken with full acknowledgment of its speculative nature and the clear understanding that there was no guaranteed return.
which would mean that you somehow became familiar with the possibility that you could lose your investment, and that you could not claim any compensation for the damage if it happened.
However, in order to clarify the legal situation, you will have to find someone who will study all the documentation in detail and then conclude whether you have legal grounds for any claims.
The ICO ended on 30 September 2017 and all ETH were invested prior to that date.
The document itself was backdated and states "This Token Crowd-Sale Agreement (this “Agreement”) is made as of this August 31st 2017 (the “Effective Date”) "
But it was created and published well after the ICO.
I actually remember this: at some point the team hired a lawyer, who I assume advised them to create said T&C and also remove some of the content they have previously published on Medium.com
It looked like damage control to me.
