Can i trust on etherium project
I want to hold it for long term 5-10 years
Can i use hardware wallet (ledger or trezor)
That's a nice idea for holding ethereum for up to 5 years it's surely gonna yield a good profits, and make sure you use an hard wallet for it don't put it on an exchange it's highly risky the best you can do is to get a wallet That you can control the private Key
