It seems like a new project that appears, OP, to me before you invest in one of the projects that you just know, you have to find information as accurate as possible, so you are not deceived.

I haven't seen any progress so far on the ycrab.finance project, you are talking about.
Someone has made a topic about the project you are referring to, but currently there are no replies or comments from those who made that topic.

You can see below.

Topic: YCRAB.FINANCE - SIMPLE YET ELEGANT PROTOCOL

Therefore, in the meantime, before going any further, you should monitor the progress of the above topic, if there is no progress in a positive direction, you should think 1000 times before giving them money.
