After their recent profit feature wherein your balance will increase for some percentage over a year, and now offering a wallet? There are lots of reputable online wallet compare to them. I don't care how much trust they build from faucet feature but using this as bitcoin wallet sounds not making sense to me.
Id rather used Coinbase or XAPO here compare to them in terms of security and assets. Freebitco is still for faucet purposes only and not as a bitcoin wallet.
The popularity of FreeBitco.in is what lets them pull this off. Tons of people are first introduced to bitcoin through it, so it's not a total lack of logic that they're offering this. Plus, they
want more funds in the wallets hosted by them so that they can have more in the reserves for claims.
