I don't get it. So people are to trust this 3rd party with what could amount to a 6, 7 or even 8 figure amount of physical coins they own. I don't know if I'd be able to sleep at night not knowing if they were safe. Don't get me wrong I'm not implying anything I just don't know about 3rd parties holding my stuff and for me to get an nft in return. What if I lost access to my nft thingy who gets the coin?
Edit: fysa if any of those coins sell on that marketplace let me know I'm down for those prices
Edit 2: always a good thing to get more visibility on physical crypto coins for sure.
Definitely a valid concern and I've thought about this a lot. I think the issue is that 1) Very few people currently use bitcointalk relative to the current size of the crypto community 2) Anyone who comes here is going to have a hard time trusting MJ or other forum based escrows since they don't have any context of the forum history or how valid the trust system is (I think they're fantastic don't get me wrong, it's just hard for someone new to process) 3) the current structure of having a 3rd party escrow hold funds then having to mail the item (and trust the receiver will confirm receipt) or fly and meet the person (which for certain values there are serious security concerns) requires coordination/trust between three parties and is quite a challenge.
I've helped a few people source Cas coins in the past and it basically amounted to me hard vouching for both parties and was quite a challenge. If something goes wrong, the package gets lost, or the anon escrow stops responding what do you do? People don't want to deal with all of these concerns and it's obvious when seeing things like that recent MS65 5 BTC auction go for under peel value. Crypto solves the trust problem in the digital domain but the physical world still unfortunately requires trust assumptions. This team is all US based, identities are all known, the items are insured, and for larger amounts there are signed contracts with known people and legal entities. This allows legal recourse if something were to go wrong. The safest choice is to keep these in a safe but when it comes to selling them, I think this is a step in the right direction. All ears if there are ways to improve it or if you think the current forum system works better for 7-8 figure transactions I'd love to hear why.
Also, some cool stuff in the works now that these can be NFT'd, this allows them to be fractionalized (can sell/own a fraction of a coin) as well as used as collateral for loans or DeFi (access liquidity without realizing capital gains). 4K will also be launching yield farming for items listed on their exchange so even just sitting they will earn an ROI.
But yeah tl;dr do your own research and 4K will need to continually build up its trust with the community as they expand. I personally am trusting them but work within your own risk tolerance.
