Situation

Today there is no ideal way for traders and crypto investors to harvest their profit in a secure manner without returning to fiat currency. Investors who momentarily wish to take profit out of the system before entering a new position, incur high fees every time they exit and re-enter. The alternative is to keep assets on an exchange or wallet, where they face the inherent security and counterparty risks of the exchange, or the market risks of holding main coins such as Bitcoin or Ethereum.

Solution

According to business requirements and increased consumer demand for cryptocurrency Intellica suggested to develop a platform, that will allow to perform operations for buying and selling cryptocurrency in exchange of widely used type of cryptocurrencies (BTC or ETH) or using wire transfer in national currency. In addition, client can buy tokens in exchange of BTC, ETH coins or national currency.
