The cost for the service for the "Pro" and "Manage" accounts will be fixed in USD, but payment is accepted in FinTab tokens (FNT). In addition there are other interactions that perfectly complement our system. P2P interaction: traders could sell the information about their crypto-portfolio through our system. In addition the rating of best traders will be compiled. Advertising platform: placement and display of advertising will be held decentralized: each user can enable or disable ads. For the ads view the user obtains tokens from the advertisers. Analytical system and recommendations for trade using Artificial Intelligence.
