Re: Grin Observer - GRN/BTC - Price Movement and Discussion

Just a heads up guys, it is not a good Idea to be Holding right now.

Grin still affords a stronger privacy model than Bitcoin or other non-privacy coins, since amounts are safely encrypted. But Mimblewimble provides a strictly weaker privacy model than Zcash or Monero. This makes it insufficient for many real-world privacy use cases.

This is not FUD, just a heads up. I'm sure the Devs will address the issue if its possible.

I havn't spent any time in looking into this but wanted to give you guys a heads up asap.
Thanks to cAPSlOcK for pointing this out.

Just so you all know and don't get blind sided.

Here is the rebuttable Dev response.

If I sold then I'm buying back.

However, it is fud. Here is a better article to read on why it is fud.

The Dragonfly research fellow might have gotten very excited on his research which was already well known from the beginning.

I supplied the responses to the article link rather than the link you supplied, my bad.

You can click the article you linked in the link I supplied here.

It's not really fuD (as it is true), if you read the Devs responses they even conform it. I personally had forgotten all about this as it was discussed pre launch and it is a known issue in the grin Lab list. It is a rehash of an old known attack vector.

Basically a full node can log all this information from the genesis and have all the connecting information. There is nothing that can be done about that currently.

The Fud is the distorted way it has been presented and the hyperbole that accompanies the information as if it is a new revelation. I wish my memory was better as I should have noticed that when I was reading the article initially.
