Ok, yes, it's good to use 2fa, but that doesn't answer the original, legitimate, question: will poloniex be the next mtgox? So far no one has given any reasons why or why not.
1. they must have billions of dollars worth of crypto in users' accounts. there is a financial incentive for them to abscond with some of it.
2. no one seems to know any of the management at poloniex. without having a reputation in the community, I find it hard to see how they can be trustworthy.
3. it is located in the US but they haven't registered with US govt/financial agencies like coinbase and others have.
4. they eliminated the trollbox. if something bad was going to happen, it makes sense to turn off communication beforehand.
I am not that familiar with mtgox: what were the warning signs before it collapsed? right now a lot of people are complaining about not being able to withdraw funds from poloniex, even waiting more than a month. I recall this being the case at mtgox as well, problems with withdrawal. anyone can make up a balance sheet showing lots of funds, but you can't know if it's there until you try to withdraw it.
1. The accumulated millions of sollars worth of cryptos as pretty much every other big bitcoin/altcoin exchange.
Just remember that in this business there is no guarantee, the biggests exchange can fall.
2. Another argument to not fully trust them, but even if the management and CEO is known there is no guarantee that exchange is legit.
I mean - everyone knows who Mark Karpeles is.
3. That does't not concerm net. Busiensses tend to avoid unnecessary burden of additional paperwork or regulations.
4. Maybe they eliminated trollbox just because it became a tube for hardcore trolls and nothing more?
