Well this happen only on Bitfinex, but now the price is 200$ almost, also for other coins happen this thing this months and after the price recover, was lucky who had buy orders at 44$.
I think it is very fortunate to be able to get a low price when they have made a profit of more than 400% in a very short time but it is very difficult to set a low price and very few people set the price. In my opinion this is an error due to exchange or BOT there was a mistake in trading, so it triggered the panic sale at that time. Anyway, BSV has recovered and we don't need to worry too much during this time
