I know http://crypto.com  seems really cool, but after looking into them, I'm pretty confident that they are a ponzi scheme. I would stay away.

$MCO cards sound too good to be true and it is probably because they are. Depending on how much $MCO you are willing to buy and lock up in "staking", you can qualify for up to 5% cash back (paid in $MCO) and a bunch of extra rewards on top of that.

A large amount of credit card rewards are paid from the high interest from other cardholders' late payments. $MCO are not credit cards, they are debit cards. While there are some debit cards that pay out rewards, they are mainly paid for by the transaction fee or by leveraging...

account balances in the bank account that the debit card is associated with. Even so, the best debit cards reward only 1% cash back. So where is the money coming from for them to be able to buy enough $MCO to pay the very high cash back rewards?

Well it's not too far away. In order to qualify for the cards in the first place, you need to buy and "Stake" $MCO in their app, where it is LOCKED UP FOR 6 MONTHS. This is a huge red flag. $MCO is a limited supply coin, but somehow they are able to assure reward payouts in $MCO

What do you think they do with that $MCO while it is locked up for 6 months??? You think they just pull money out of their ass to give to people for using their cards? Their business model is broken. The only place where money enters their business is through the $MCO lockup.

So what is probably happening, because I can't think of a way in which this is not the case, is they are taking $MCO from the users that have locked it up with them, and are paying the rewards out to the other users and giving it to earlier users when their lockup ends

And this is just covering the cards. I haven't looked into the $CRO, but the fact that they are guaranteeing 16-18% annually for staking that token and it has a chart that looks like this is a dead giveaway that something isn't right there either.

It's a shame too, because I could really benefit from a debit card that I deposit crypto on and then use for every day shopping. But the rewards system says it all. There's no way they can pay out those rewards without this being a ponzi scheme. Unless I'm missing something big.

Another big red flag is that what they call "staking" really isn't staking at all. It is a black box where you put money in, wait 6 months, and out comes more money. It is just Bitconnect with more bells and whistles

I want to cover my ass here. I do not have any evidence of them being fraudulent. From what I understand about their business model, I believe it is impossible for it to operate unless it is a Ponzi scheme. I could be wrong. I don't think I am, but I could be. I don't trust them

They have many many red flags that would signal they are a ponzi that I listed out. If they are not a scam, then I do not know how they are doing what they are doing. I don't trust them and I won't be signing up with them. You can decide for yourselves about them.
