There are hundreds of altcoins. How do you people do when you trade with altcoins? Do you have to install a new software for every altcoin you trade?
For Proof or Work coins , I leave it on the exchanges, as they don't earn any reward for keeping them directly on my PC.
(Keep your PoW Coins split between more than one exchange , that way if the exchange crashes , you don't lose all of your coins.)
For Proof of Stake coins like
ZEIT , Noblecoin, Hobonickel, & Bottlecaps,
it is smart to download and install their wallets, as you can stake and earn more.
