As you can see all these staking are from top exchanges, my advice is to stay away from low rated exchanges that offers staking service, very soon they will claim to offer same service as well, if you have something else to add on the list pls do
I am interested with staking ATOM coin because price keep higher and stable more than last two month, but any one know how much percent allocation for ATOM staking coin on Huobi Wallet, how long time period to get staking coin will be one month or shortest than other staking coin with Binance for xlm, last two week I got ATOM raised with higher price about 5% for coin growing up.
