Digital asset investment firm CoinShares has launched two new physically-backed exchange-traded products (ETPs), one for Tezos ($XTZ) and one for Polkadot ($DOT). Both the ETPs will be listed on Germany’s Xetra exchange and will offer investors direct access to crypto assets relying on Proof-of-Stake (PoS) consensus algorithms, which means token holders can stake their coins in a bid to help secure the network and get rewarded for doing so.
