I have 3-4 coins wallet , but some wallets are good but some have problems frequently its affecting my staking rewards
How can we help you if you're not providing enough details here? What wallets are you talking about? And I don't understand how it can affect your rewards because a wallet simple functions to store your coins?
If you're trying to say that your coins has been affected in anyway like receiving less stakes as expected then its not the wallets problem. And if you have frequent problem with a certain wallet then why not shift to a more secured one?
I am thinking to shift to new wallet , i did read an article about wallet securing i will try that once thanks
