Messenger Telegram begins to pre-sell the Gram tokens of the future Telegram Open Network platform (TON). Demand for its tokens is fantastic, sources claim.

Telegram intends to attract $850 million during the pre-sale, Russian business newspaper Vedomosti reports, citing three sources, one of which holds negotiations with the organizers of the Telegram ICO.

According to them, the book of pre-ICO is oversubscribed so much that the Telegram management refuses some investment proposals, including those from Russian investors.

Pavel Durov, the founder of Telegram, intends to build a global company so that investors will be chosen according to the principle of proximity to the messenger's leadership and the investor's reputation.

The minimum investment for investors, willing to participate in pre-sale, is $20 million. Anchor investors are advised to invest at least $50 million.

Earlier, TechCrunch reported that the project of TON blockchain-based platform attracted the interest of Mail.Ru Group, founded by Russian billionaire Yury Milner. Milner's representative then did not comment on these rumors.

Durov himself has been silent for almost a month and did not confirm, neither deny the information about the forthcoming initial coin offering. He only confined himself of pointing out those resources about ICOs that are fake. So, recently he called a "scam". That web site, by the time of Durov's tweet, has already managed to collect more than $4 million in cryptocurrencies for supposedly pre-selling Gram tokens.
