The BTC is quite safe, but you are still wary of having multiple hackers installed on your computer to steal your private key.
Yes of course. Bitcoin and its technology used make it more safe, to protect accounts of users and its transactions made. But, it also depends on the users who have their accounts secured, how they keep their private keys protected. For me, its better to use more wallets to separately put my bitcoin or earnings, because hackers are only interested on big amounts.
