I'm not following you, that quote basically says what I said.
Grin creates more fungible coins as it destroys the links (transactions) automatically but you also have a trade off by not being able to prove a past transaction.
I'm not sure what effect Monero's pruning will have but I think there will still be full nodes with non pruned chains. TBH I don't remember and am not going to go an re-read it.
Lets reduce to this
Basically, Monero has three privacy protocols. Ring signatures, stealth addresses, and ringCT. However, stealth addresses and CT are the only parts that are absolutely essential to privacy. Ring signatures are great for the paranoid, but they actually arent completely necessary. Theyre wonderful, but theyre also redundant. Grin strips these away and leaves only stealth addresses and confidential transactions. An observer still cant derive any useful information from a Grin transaction, and the fact that Grin allows transactions to aggregate, or merge together, makes it even harder to trace.Monero have 3 Grin 2. Blockhain analysis will break through. Maybe they will fix it. If they will maybe that will be Monero next solution.
This is actually first time I am reading someone propose that grin is less traceable as Monero. Here is what someone else says:


The bolded above is exactly what I said, so you are confusing me here.
I am speaking in terms of chain analysis, not tracing a transaction while its in progress (I have no clue about that) But, like I said
From what I understand of mimblewimble is there are no records kept which yes will make for great fungability but how can you prove you made a transaction in the past?
Everything in life is a tradeoff and you need to choose by what balance you are willing to accept. If you want a fully transparent ledger then BTC is top dog for the job./quote]
If I am incorrect in this understanding then explain to me how? All I have done is a cursory investigation of grin over a year ago so it's not like I propose to be an expert nor a supporter. Although I do support ALL tools to keep an individuals personal information private.
