I want to invest in good quantity. but it is very hard to rely on hardwallets. MyEthWallet seem good in terms of ease of availability. I need to know if it is enough safe to use MEW?
I think you should be careful when saving your assets, many fraud sites will get your private key, I advise you to use Metamask when you want to make a transaction, it will keep your assets safe from phishing sites, you can visit phishing sites that are still active until now
