What is the best desktop wallet for store altcoins those are not support to trezor or Ledger nano ?
For your own sake do not use webwallets or app wallets because they are more prone to hackers,computers are more easily to get compromised by these hackers while app wallets are too risky to use because these are just like webwallets that might be hacked using malwares or viruses.For me the best thing to do is to have a cold storage or atleast a paperwallet if your hardwallet doesnt support most of your coins.
