Is there a wallet we can use to store Bitcoin and all other assets such as LTC, ETH, DASH, DCR?
I recommend coinbase it is safe to store your wallet and this wallet have ethereum wallet also but they dont have LTC, Dash or even DCR. I store my LTc and dash to the exchanges site like poloniex and bittrex . I dont know what is the name of wallet of that coin. BUT I THINK THEY HAVE APP FOR THAT YOU CAN DOWNLOAD THAT ON PLAYSTORE.
LOL. Do you know what a coinbase wallet is? Coinbase is exchange so they wont let you have the private keys, meaning you don't have control over your bitcoin. If they are hacked tomorrow, say bye-bye to your hard earn bitcoins.
As for me, exodus is the best option to the OP, it looks user friendly and customizable and can hold several different coins at the same time. I think the link has been provided below. You may want to look at it. Goodluck!!!
