One of easiest way to create and access Ethereum and erc20 token is MEW web interface. My question is , is it safe to keep big amount in MEW or better not to rely on it.
Never Let Big amount stays in Wallets that you don't Own your Private keys so it is not that safe either.
Why not instead of MEW use a LEdger wallet that you can be 100% sure of being safe.
and besides if you have big amount of currencies/tokens then better diversify them all to multiple wallet for more safer hiding , at least if one chance you become a target of hackers then at least only one of your funds will be at risk.
