What kind of wallet will you advise? a purse should support different coins on different block. It is necessary that it be reliable and with two-factor authentication. 
As far as my knowledge hardware wallets are best but it will cost us a little bit so buy an hardware wallet and keep all your funds at your hand completely safe or you can download official wallet for the coins if they have something for each.But Ledger Nano looks like the best and secured wallet for me.
