The promise of anonymity day by day will be long gone
Anonymity with bitcoin was never promised, but it remains entirely possible to remain anonymous when buying, selling, trading, or using bitcoin, if you have the will to do so. Using decentralized peer to peer trading, trading using untraceable fiat methods, never completing KYC, mixing your coins, and doing all this over Tor, is a good start.
If you don't exceed on the exchange average daily or monthly limit they will not require a KYC procedure to you
That's just not true. Plenty of exchanges lock accounts and demand KYC from users who are nowhere near their trading limits because they have triggered some unspecified algorithm and the exchanges has decided they are "high risk".
Phone number and email were required for unverified users. But I don't consider them KYC. Those information do not reveal who I am.
Given the amount of information most people freely give out to various social media sites, and how many databases of personal information have been sold, leaked, or hacked, a phone number and an email is usually more than enough to identify someone.
