Is it safe to deposit yet? I've not heard anything since that last alert they sent out last week...

Only their hot wallet was hacked (~0.6%) and they said they will reimburse all stolen funds. I wouldn't worry too much.

I think so, but their website says you shouldn't deposit to old Bitfinex addresses. Generate a new Bitfinex address to deposit to.

Dear Customer although we keep over 99.5% of users' BTC deposits in secure multisig wallets, the small remaining amount in coins in our hot wallet are theoretically vulnerable to attack. We believe that our hot wallet keys might have been compromised and ask that all of our customer cease depositing cryptocurrency to old deposits addresses. We are in the process of creating a new hot wallet and will advise within the next few hours. Although this incident is unfortunate, its scale is small and will be fully absorbed by the company. Thanks a lot for your patience and comprehension. Bitfinex Team

Yes, Bitfinex is fine.  When you deposit, just have them issue you a fresh deposit address

What is Bitfinex, I never heard about it before. Is this kind of a Bitcoin Investment site? And, how does it works?

Bitfinex is an online exchange and trading platform, not some kind of bitcoin investment site.

Depends - you can lend to other people who will then use the lent money to trade. Obviously you lend with an interest rate, but you take risk in that if you lend in USD and the USD rate rises significantly, you can end up with less Bitcoin then you started with and vice versa.

The platform itself seems secure enough, besides the recent hack then. Any exchange is a risk when it comes to storing funds long-term though.

BFX is actually good, as compared to other exchanges which just give fake promises and never come up to help out their customers in case some serious hacks take place and security gets affected...

I reckon is pretty much as safe as you can get in the bitcoin world.  I'd made both withdraws and deposit since the hack, doesn't look like anything much has changed, they just take the hit since its small time for them.
