I never partecipate on a ICO, and I found this very interesting.

However, I am reading on Rentberry_Terms_of_Token_Sale.pdf this:

"Not an Investment. Purchaser should not participate in the BERRY Token Sale
or Purchase BERRY Tokens for investment purposes. The Purchase of BERRY
Tokens pursuant to this Agreement is not designed for investment purposes
and should not be considered as a type of investment. BERRY Tokens may not
be transferred until the end of the Sale Period and are subject to certain vesting
periods as set forth below in Exhibit A. Purchaser acknowledges, understands
and agrees that Purchaser should not expect, and there is no guarantee or
representation or warranty by Rentberry, that (a) BERRY Tokens will be listed for
trading on any exchange, or (b) the Rentberry Platform will be adopted as
described in the White Paper and not in a different or modified form."

If there is not any guarantee that will be listen on exchange or that WP will be adopted, how we can trust this?

Also why can not be an investment?

Or maybe all ICO have this terms?
