Hello experts,

I have four questions:

1) How do I know if certain coins/tokens are supported by MEW and therefore I can store them in that wallet?
2) Do I need to back-up the JSON file everytime after I send new tokens to the wallet?
3) Is there a private key or something like that in the case I would lose the JSON file? (It is safely stored though)
4) Why would you use a hardware wallet instead of myetherwallet? (given that you only have coins that are supported by mew)

Thanks in advance,
