A few days ago i reported about the DEFICHAIN platform. This is the place where you can start with a bonus of 30$ when you use the referral link. But it is to say, that you will make at least one deposit. You can do this via ETH, BTC, Theter or something else. And no there is no minimum amount required. Keep in mind, that your bonus will be frozen for 30 days in a staking pool. After that you can redeem your DFI coins wherever you want or you want to stake them I don`t know it is your decision.
New Exchange lists DFI token
And yesterday a new Exchange, called KUCOIN listed the DFI Token. At the moment there are pairs for DFI/USDT and DFI/BTC. For more informatin please see the attached picture, dated from 22.01.2021 : Coingecko Link: https://www.coingecko.com/en/coins/defichain#markets 
KuCoin
And yes Kucoin is a well know Exchange for cryptocurrencies. The outprint theirself as one of the greatest exchanges. Kucoin also offers their own token. From my point of view many exchanges in thouse times are dooing the same. But the interrestig thing is that you need at least 6 Kucoins, to get the rewards on a daily rate. I had given it a try and this is what i got. Now much but it is enough to let them on their exchange for a while.

Summary
So DFI is now listed on Kucoin. And Kucoin is an exchange where you can trade cryptocurrencies only. I am not sure if it is possible to exchange FIAT in Ether but at the moment i have not found a way. The second option is to buy some KuCoin Coins (KCS) and earn some rewards on a daily base. I also added my affiliate links, which offers a bonus for you and me. All the best and stay save and healthy in those times.
