Having lived through a few "socialised losses" over the years, I remain somewhat sceptical. That initial ~10% could represent the easiest funds to recover from overdrawn accounts, or perhaps a portion of Poloniex's reserves/operating funds.
At least they seem to be repaying in BTC - like for like - rather than some internal token which has its value fixed to the exchange rate on the day of the event.
With Poloniex?
I think I've had some money in my lending wallet at Poloniex continuously since mid 2016. I had never experienced any "socialized loss". Do you think I was lucky? Anyway, I'm still missing 90% of the 16% Poloniex seized from my account, and that's substantial money. So I'm not so lucky...
I've been affected by losses at mtgox, Vircurex, bter, Cryptsy, Cryptopia, etc. Some are fairly absolute (such as Cryptsy abruptly going out of business) but others have been some event (such as a hack) which resulted in "haircuts" being applied to customer balances.
So I was speaking generally about past events with other exchanges, not specifically Poloniex. Sorry for not making that clear.
OK, thanks.
I've always been very, very cautious about choosing exchanges.
I've used Poloniex, Bitfinex, Binance and Kraken. That's it.
And I've never had any bad experiences, besides a few delays when making deposits or withdrawals.
Poloniex was my first bad experience (after several good years)! And I hope the last...
