Just want to shine some light on what's happening with Bytecoin (BCN), as it is one of the more sophisticated pump and dumps.
So let me first briefly tell you what happened. Earlier today BCN was trading at around 72 satoshi on both HitBTC and Poloniex, quickly increasing 30% when the news of the Binance listing came along. It opened on Binance at around 300 satoshi and over the past few hours the price has risen to 2320 satoshi on Binance, whereas the current price on HitBTC and Poloniex is at 190 satoshi. To put this into perspective, the circulating supply of BCN is 183,878,867,869 (taken from CMC), whereas the current price on Binance is 0.22$. This puts BCN on a market cap of 40 billion $; right on the third position, between Ethereum and Ripple.
I've been following it closely and found that withdrawals from HitBTC and Poloniex were not working nor was the BCN webwallet. When checking their blockchain explorer we find that no new blocks have been mined for the past 2 hours. The trading on BCN started at 06:02 UTC and since that time only 46 blocks have been mined, containing a total of 997 transactions. The number of transactions that went through seems very small for a coin that just went up over 32x in a few hours.
Thus most investors are not actually able to sell their BCN on Binance. The current BCN supply that's on Binance is very low and therefore it's easy to pump up the price, all the way up to 20x it's original price. This still caused a 150%+ surge on exchanges such as HitBTC and Poloniex.
Not saying that the Bytecoin team is involved, but it seems very shady that their coin got listed at a time that (nearly) no one is able to move the token towards Binance. More importantly I think it's curious that Binance still listed a coin that is (nearly) impossible to move around and thus easy to manipulate. We've seen the same kind of pumps happening on coins that couldn't be moved around, for example Bitcoin Diamond.
Of course, these things happen in unregulated markets. However I think that Binance should take a stance on this, as these kind of events hurt the reputation of the crypto markets. Especially the regular joe will get burned trading a coin like this.
