in almost 4 years of existence there isn't even 1, online shop which accepts this coin, even dark web shop doesn't accept it, anonymous  entities create it, and they don't want that
ONION will be on Dark shops, because the  team doesn't want that this coin will be connected  with "Dark shop`s". Then for what is this coin?
something is really broken in the philosophy of this coin  

Listing on Kucoin back in 2017 been one time a miracle, when a community has huge, now "there isn`t community anymore,just few "anonymous identities with many excuses AKA
*that ex mod`s dumped much, so they crash price,
* that if you want to get rich with this coin you need wait, probably 4 years of waiting is too less, another 5 years should be ok.
* that some Kucoin employe had hidden agenda and  help delist it from there,
* that people don`t see potential in Deepvault, which is useless and overrun by time,
DeepVault is useless,is only for small video`s, pictures, some text file, they say that court`s  can use it, ok, the court will ask a  patent number of DeepVault, where is??

this is the real stuff:   https://www.acronis.com/en-us/technology/blockchain-notary/

what real block chain notary like ACRONIS have:

Acronis has 18 offices worldwide. Its R&D centers, Acronis Labs, are based in the United States and Singapore

So there are better solutions than Deep Vault,

what real privacy coin like XMR have;

There are over 180 contributors to the Monero project. See the Monero roadmap here.

ONION is project of maybe 10 people who lose touch with reality, they still wrote some codes, but all is in vain, This project has already lost community

Just don`t put some serious money in this project,
