Im thinking of trying this eidoo wallet, but before that I want to get some info because of fear that it might be scam.
Dude, if you think it is scam you shouldn't even think to store your funds in there.
Do you have any recommendation for eth wallet at the same time support erc20 token?
I don't think you need to search further than this:
https://www.myetherwallet.com +
metamask extension.
Or hardware wallets
ledger nano s or
trezor.
+1 on this, what advantage do you get by using a wallet app vs the risk of bug, hack, etc? Integrated trading or some other feature? At least for holding you only need your eth address.
