https://bitcointalk.org/index.php?topic=5261357.0it tackles about Casinos that offers staking also and maybe since you are asking about Platforms and no specifically ? maybe you will consider some of the casinos as best place to stake your money.
Exchanges like Binance, Kraken and Kucoin offers staking features but its not actually that much profitable like trading the crypto assets and when your assets are on staking period the value of assets can drop drastically which is the biggest risk associated with crypto staking.
binance has a good offers for staking in Ripple(XRP)
but OP must consider looking for the coins he wanted to stake and not just the platform itself.
