Withdrawals from Hive Engine not working

So, about 14 hours ago I sold some layer 2 coins for Hive, and initiated a withdrawal to Hive so I could transfer it to savings - and it never arrived.

It's only a tiny tiny amount, but ever since the demise of Ionomy (where I lost several hundred dollars when it stopped working without notice), I've become hyper-sensitive to exchanges failing.

The egregious thing about Ionomy is they didn't tell anyone they would be shutting down. They let people log in, make deposits, initiate withdrawals, without telling anyone they'd disabled the wallets from the exchange. So your deposits were on the blockchain but not showing up on the exchange. And you confirmed your withdrawal but nothing got sent. And there was no notice to alert the unwary.

I thought Dex's like Hive-engine would be safer, but now I'm learning they're only as good as the counterparty. If the counterparty decides not to send the coins, you are screwed.

I'm not sure what the answer is. British people can't use Binance. Bittrex and Poloniex are dead. Ionomy is not only dead, but scammed people of anything they held there.

I had thought a Dex like Hive-engine was the answer, but clearly not; they didn't even put a notice on the withdrawals page saying there was a delay, which is what people usually do if they are genuine. Nothing, nada.

I suppose the next step is to try out Tribaldex and hope they work. https://tribaldex.com/

My advice to everyone is to send a small test amount before you send anything more. And do this every single time, even though it's a pain.

Crypto specialises in the long con where they lull you into complacency. You never know when it is going to stop working. I'm cross this evening, but I'm not out of pocket as I sent (and lost) only a tiny tiny test amount.
