but not full safe, because coinbase not support private key, if coinbase service close or gone, you can do it anyhing and bitcoin balance is gone too
Yes agree, I am user of coinbase about 2 years, and until now have never found a problem. Certainly by activating 2FA is the best solution to increase security, but we must be aware that the web wallet is not secure 100%, so coinbase I use to store bitcoin no more than 10 btc.
10 Bitcoin is huge money man. For storing 10 BTC in coinbase wallet is not safe and secure. You can use hardware and desktop wallet for storing 10 BTC . Those wallet are 100% safe i have heared.
