    Easy to fit into our existing process

    We were looking for a way to accept crypto payments with no changes to the rest of our workflow. After reviewing payment gateways, 0xProcessing was deemed more feasible than others. The setup was simple and once it ran, never required day-to-day attention. The ability to create payment requests is hassle-free and clear for daily transaction uses; hence, there is no confusion.

    ๐Ÿ Competitors: CoinGate, RIZON
    ๐Ÿ‘ Pros:    Quick to get started|Supports multiple cryptocurrencies|Simple payment request|Clear transaction status
    ๐Ÿ‘Ž Cons:    More detailed reporting would be useful|Dashboard customization is limited
  2. Cimin Cohen
    ยท Founder and CEO at Idea Peddler ยท
    The goal is to move BitPay in order to utilize it globally.

    Following numerous payment drops and unexpected compliance holds with BitPay, we switched our primary checkout flow to 0xProcessing. Our global clients rely on cross-border technology, services, and products. We needed a payment gateway that is used to handling payment processing and wonโ€™t raise flags about something this usual. Actually the onboarding as merchant was quite easy. The API integration into Vettrackโ€™s custom billing stack has taken the dev team the best part of about two afternoons and the docs donโ€™t leave much to the imagination.

    To run its day-to-day operations, Stable is used. We rely heavily on this payment links feature, which is completely automated. The VRCS feature converts incoming volatile assets to stablecoins automatically. The latter aspect alone has given adequate protection to our margins during the dips which get tied up in the afternoon. The 18 supported networks includes nearly everything our clients use. The processing time in so minimal, and we have still yet to have our first chargeback or false fraud flag since we started using it. The interface is effective but has glitches.

    ๐Ÿ Competitors: BitPay, CoinGate, RIZON, Coinbase
    ๐Ÿ‘ Pros:    Vrcs effectively mitigates market volatility risk|Supports a wide range of native tokens and|Transparent fee structure with no hidden billing surprises
    ๐Ÿ‘Ž Cons:    Ui dashboard feels overly basic for complex financial analysis|No native fiat payout options available

    A practical option for making crypto payments on occasion.

    Since we don't usually process such payments, we werenโ€™t looking for one that was equipped with many sophisticated tools. The first things were reliability and setup that shouldnโ€™t be hard to get used to.

    After looking at a number of options Fireblocks included we found 0xProcessing easier to work with. The on-boarding process was simple and the documentation covered the majority of our needs. It has been doing its job with no additional work since implementation.

    ๐Ÿ Competitors: CoinGate, Fireblocks, BitPay
    ๐Ÿ‘ Pros:    Straightforward on-boarding|Supports several networks|Easy to understand pricing
    ๐Ÿ‘Ž Cons:    Limited analytics|Few dashboard customization options

    I found Waking Up to require more effort than calm.com (or headspace). The latter apps tend to focus on simple things: e.g. Focus on your breathing whereas Waking Up is actually much more about challenging your beliefs of what it even means to exist. Source: almost 4 years ago

    I don't do full yoga but trying out calm.com and just some mind clearing meditation daily is great for unclenching the upper stomach muscles around the diaphragm that you don't realize clench from day-to-day stress. I remember wanting to try it when I was younger because I've always had an issue with holding onto anger and frustration but was told the whole "emptying your mind lets Satan in" business.
