I want to hold it for long term 5-10 years
Can i use hardware wallet (ledger or trezor)?
Ethereum is one of the best project in crypto industry, and widely accepted currency, and as you can see almost all of the tokens out there used the ethereum blockchain, and or ERC 20 based tokens and concept, so i bet this is by far, one of the most recommended cryptocurrency to buy, next to bitcoin, i just hope you can make a study before investing to any cryptocurrency out there, because a lot of tokens and coins are promising at first and in the long run, they were abandoned and slightly die.
