He also blinded the public key behind two different hash algorithms[1] for display as an address (RIPEMD-160 & SHA256). The public key of an address is only revealed in the output script when spending funds held by that address. Thus, with proper wallet behavior surrounding address reuse, your EC public key vulnerable for a short period.
Now, the private key must be secured properly, but that's the case with any crypto system.
A future mathematical weakness in RSA/DSA could have been a concern, but 2 larger reasons to use EC in BTC are that a) signature computation is much faster, b) almost every 256-bit value is a valid key, allowing fast key generation that supports the (often ignored) recommendation to use a new key for each transaction.
