Yes, I also sell mintcoin for 0.00000020 in Mintpal, because I think I would buy for 0.00000015 on CoinMarket. And you f... me, so I lost some millions mint. Thanks for that!!
Use common sense. Hundreds of people and only ~10 BTC worth of cheap MINT was avalible. It was gone in 15 seconds.
I thought he was saying he went to withdraw on one exchange and deposit into coinsmarket and when he went to buy the coins at coinsmarket, they fucked him, saying then and only then when you purchased the coins, that they were under maintenance. That's not bad investing, that's bad site practices....
Displaying a low price for a coin that other exchanges keep live prices on, and then allowing for deposits tricking people into thinking they could get cheaper coins is not too cool. I am posting this, since people are thinking it's all dandy Jandy...
Since you shouldn't even ALLOW DEPOSITS AND WITHDRAWS if a EXCHANGE SITE IS IN MAINTENANCE....
Or, you could deposit the coins, realise that trading was suspended, send the coins back to the original exchange and grumble over lost transaction fees. Since you couldn't put in new bids, but you could cancel your asks, I just don't see how you can manage to lose more than transaction + trading fees, even if you can't be bothered to read the very obvious "No trading becuse of maintenance" message.
