The reason is that Allcoin is a shadey chinese exchange so nobody leaves their btc onsite. I'm thinking people just go in, buy and withdraw, that's what I do there.
Price is rising but buy support is low on Allcoin. I suggest waiting to sell until buy orders fill in more, any big sell right now would crash the price and leave the seller with half the profits he/she would have had if they had waited. Or wait until it hits a big exchange and volume increases.
See price now, like I said, low buy support. If you're longterm you shouldn't worry about price at least until it gets picked up by coinmarketcap and a big exchange. Currently a lot of 1 coin orders filling in gaps between buy and sell which inflates the price.
, or you can sell all your coins to us, that works too.
