Can i trust on etherium project
I want to hold it for long term 5-10 years
It's no longer profitable to invest for the long term as those days are gone.
Can i use hardware wallet (ledger or trezor)?
It seems these wallets are the most recommended wallets these days and I haven't heard of instances of people losing coins stored on these bad boys as opposed to using private keys which could be stolen by clipboard viruses.
