Para sa akin, any hot wallet na may access ka sa private keys mo are ok.
I would go against storing your bitcoin sa Coins.ph na wallet kung di mo gagamitin dahil wala kang access sa private keys mo.
I personally like Jaxx (
https://jaxx.io/) wallet kasi multi-coin and at the same time HD (Hierarchical Deterministic) wallet ito. Nakikita ko lahat ng private keys ko for Bitcoin, Ethereum, Litecoin, Dash and other coins. May desktop version din ang Jaxx so pwede ko ring ma check ang holdings ko via my laptop and desktop.
But the best for security wallets are the cold wallets like Ledger, KeepKey and Trezor.
