This question may have been asked elsewhere but I haven't been unable to find it and hopefully this is the correct place to ask. If not forgive me.
I know you can have multiple ERC20 tokens in one ethereum wallet, but is this wise to do? Should I be transferring each token to its own ethereum address? I've been trading the older cryptocurrenies (bitcoin, ether, litcoin, etc.) but I am now looking at a few tokens to purchase and have successfully participate in a couple of airdrops and I am trying to figure out the most prudent thing to do. It's obviously easier to track them holding them in one wallet. It may not make a difference either way but any thoughts would be appreciated.
There are pros and cons to both methods.
If you send each token to its own wallet, you will lose less money if you lose access to an address through hacking or simply losing the private key. However, the more tokens you have the more difficult it will become to keep track of all your private keys, so it might become easier to lose access to some of your wallets.
On the other hand, keeping all tokens on one address would mean that you lose all your funds if you lose access to your private key or fall victim to a hack or phishing attack. But it's also easier to keep track of a single wallet.
Depending on how much you're investing (and on how you are planning to deal with taxes), you might want to consider a mixed approach.
