After this bitfinex hack...I decided it was time for cold storage...I had a lot of bitcoins sitting on coinbase wallet...I set up trezor this morning and moved my bitcoin....easy to setup and use...now I can relax.I will just use coinbase to buy and sell bitcoins but not to store bitcoins.
it is an good decision to save the bitcoin on cold storage , i also would like save it on cold storage , i believe that will be the safer than keeping it on online wallet . because online wallet sites should adopt more security features on their sites.
