Since I have no deep understanding of the possibilities of storing crypto-currencies I have some questions which I posted already in some other thread. However didn't get any answers so far.
Actually everyone recommends to use hardware wallets, however I have some questions regarding that topic:

1. Where do most people store there less known Altcoins? Since many of the Altcoins are not supported so far by the hardware wallets.

2. How can I be sure that a newly purchased hardware wallet was not corrupted from the manufacturer or a middle man who is selling the wallet?

3. If I use a software wallet, how can I be sure the file is safe to use? Is there a kind of checksum or any other good method for securing the file is safe to use?

4. If I use multiple software wallets on one laptop which I setup for wallets only and one wallet would be corrupted, isn't there a big chance to loose everything?

Thanks for your help!
