Tezos' Liquid PoS consensus algorithm makes it real easy to get staking rewards for anyone who holds XTZ. Liquid PoS, gives holders the opportunity to bake (run a node) or delegate (point your XTZ towards a baker who will then receive, a small percentage of your rewards) their XTZ and earn a yearly return in XTZ of about 5.5%.
Until recently you needed to hold your XTZ in one of the available Tezos wallets to be able to delegate your XTZ. Exchanges like Coinbase, Kraken and OKEx have just added the opportunity for people who hold their XTZ on an exchange, to delegate their coins and earn rewards on these exchanges.
Soon after, the main Swiss stock exchange SIX, launched an Exchange Traded Product (ETP), fully backed by Tezos (XTZ). The ETP is called AXTZ and every AXTZ is backed by 1 XTZ, which is held, secured and managed by the Coinbase Custody platform. Holders of AXTZ will profit from Tezos LPoS too, by earning rewards of the baked XTZ's that back the ETP.
Today, next in line, Atomic Wallet added Tezos staking option, making it possible to delegate XTZ that you hold on the Atomic Wallet. See here for more information on Atomic Wallet.
