Supposedly Telegram is also having a second stage of funding, which would probably put it over the $1 billion mark. This would make the market cap of the Telegram token already higher than some quite established tokens including Steem and Verge, and approaching the market cap of tether. I suspect once the Telegram ICO is finished the token value will drop quite rapidly, as I can't remember any coin having a >$1B market cap instantly. The ROI on this seems very low to me, at least in the short term.
Thank you for your opinion, but i still don't understand a bit, why you've said that the value will drop. The huge market cap will stabilize the value, won't it?
