I only used coins.ph. as what i know its the only trusted btc wallet here in philippines.
I used COLD STORAGE as my wallet even tough its offline i can guarantee my safetyness and security of my bitcoin because for me its 100 % trust and its really safe. And in online wallet i don't have many knowledge and know about the online wallet but i heard that many in online wallet were has virus and some there are virus and steal your bitcoin right away from you
