"PBC Confidential Profit Sell Alert
Today, we’re closing our position in Tierion (TNT).
We first recommended TNT in May 2019. It’s also part of our Five Coins to $5 Million portfolio.
As you’ll recall, Tierion’s main product is Chainpoint, a standard for recording and verifying data on the blockchain without relying on a trusted third party.
While we still like the Chainpoint product, information has come to our attention requiring us to sell TNT.
We’ll follow up with a detailed explanation. For now, let’s exit our position.
At TNT’s current price of 11 cents, we’re selling for a 383% gain."
