Cryptonetic
Why Cryptonetic?
• The top 100 wallets hold 18% of Bitcoin's value. The biggest players can easily control the market at the expense of millions of smaller investors. Join the revolution and defy the establishment!
How does Cryptonetic work?
• It's very simple—earn trust tokens on the Cryptonetic platform and spend them by voting for cryptocurrencies you believe in. Trust tokens reflect your belief in the value of a particular project. For 50% of the value of each deposit, we will purchase the cryptocurrency you voted for. At the end of each month, we will draw users to win cryptocurrencies purchased with trust tokens.
What is Cryptonetic?
• Cryptonetic is an infinite map that lists all cryptocurrencies, and cryptocurrency exchanges, sorted by the trust people have in them. You will find detailed information about cryptocurrencies such as trading volume, volume, exchange rate, and position on our list. We will help you decide which cryptocurrency exchange to choose based on information such as the number of cryptocurrencies available, stable coins, daily volume, and market/taker commission.
