platforms like cryptotalk may be available for them,
That site is no way in compare to other crypto-related forums and its considered as dead, almost no new post there upon checking it. Bitcoingarden or altcointalk and reddit is much more considerable than that cryptotalk.
But i wonder how many people or user of those website actually care about their privacy? At least on this forum, we know some member claim they take privacy seriously (some even on paranoid level).
