Tho I wouldn' stick up too much to wallets which I don't have full control with just because they are the ones who are shouldering the fee. Security is much more to weight. So, just so you don't know, if you are storing big money then avoid using web wallet.
I'm also using Coins.ph but no, only if I'm selling BTCBTCBTC. I don't hold funds in there. You're better off using a BlockChain wallet.
I've said this before but I wanted to repeat it again.
Coins.ph wallet sucks! There are numerous reports against on them stating that there are missing balances on some users' wallet. Not sure though if its just an isolated incident or not. Either way , avoid that site to be more safe.
Few days past the news spread that coins.ph are scam they reduce their balance every day.. and i think they're used the script spreading in facebook group and forums..
Honestly i never trust all online wallet even blockchain because there a chance that our wallet can hack and get our balance..
Its better to use offline wallet or cold storage so that you are far from any hackers online.. also we don't know when online wallet will shutdown in the future so offline or cold storage is the best for me..
