Hello everyone,
So I'll try to answer the questions here:
By large withdrawals we mean 100,000 USD worth of BTC or LTC. With price increase, this limit is getting lower and lower in BTC or LTC term so we might adjust it.
You might also run into an empty hot wallet and in this case it takes a few hours to replenish it (as deposits goes directly into cold wallet).
About the insurance funds, we have no such plan for now. We prefer to ensure the insurance will never been put into use, as the concept of this insurance is not attractive to investors (it's a 0 to 5% a year for a 100% loss risk).
ABout BTC deposits taking too long, here is the situation: As you know, we use Armory as the client to manage the deposits. This is a great client, that provides a good level of security. However it has one tiny problem: it is very unstable. Sometimes it crashes, and in this case it is automatically restarted (it takes 15 minutes to be fully restarted, those who use Armory will understand why). But sometimes, it also just "freezes" in a unusable state, in which case we have to manually restart it.
As our activity increases, it is more and more unstable (today it has been restarted twice). We are considering new options, but of course this has to be carefully planned as security is the first requirement of Bitfinex.
Don't worry though, the funds are never lost, as the technology behind is Bitcoin, which, as you know, is quite awesome
Thanks for other suggestions as well, we always take note of it.
A small word about the yesterday maintenance: we have now increased our capacity and will slowly upgrade the code to make us of them. Consider the migration as completed.
As all Bitcoin exchanges these days, Bitfinex is experimenting a noticeable growth, thanks to you. So a big thank you to you all
Have a good day
