# Problems & Motivations

Satoshi would wake from his grave, if aware of how people are acquiring Bitcoins on Central Exchanges.

* Centralized Exchanges (CEX) requests lots of private documents, from IDs to proofs of income.
* Those who buy cryptocurrency on Exchanges are *never anonymous*.
* * It is unclear how Exchanges use their client's personal & private data.
  * Mostly wallets and posterior transfers can be tracked by Exchanges and odd legislators.
* CEXs like MercadoBitcoin in Brazil have millions of clients and very expensive trade taxes.
  * They follow heavy regulations, and traders might become marked as crypto-owners by our IRS.
  * Their founders became billionaires but no Fund is shared among its users or communities.
* Most centralized platforms connecting sellers & buyers are full of scams and fraudsters.
* * On personal experiences, our team lost more than 2k on localbitcoin and other online groups.
    * "Someone used a hacked Paypal account to buy my crypto and had their money back in 48h"  
* Cryptocurrencies on some "p2p" platforms in Brazil can be up to 35% more expensive than on CEX.
* We are part of an online group providing a "relatively reliable" *friend-of-friends* network of traders. 
  * Most F-of-F solutions request a day-before BRL deposit and a later conversion and transfer.
  * Less bad, but it also doesn't give any guarantees of anonymity or protects the person behind it. 
  * It also has a very limited number of possible crypto/tokens to acquire.
* On November 2020 the Brazilian Central Bank released a new payment system called PIX.
  * This experimental system (we read the papers) enables transfers in seconds over Qr-code.
  * Surprisingly**,** it implements the new privacy [LGPD law](https://iapp.org/news/a/an-overview-of-brazils-lgpd/), presenting the depositor's name only.
* It is time to build a Solution!
