Poloniex has announced its plans to delist 17 cryptocurrencies on its official Twitter page.
"On May 2, 2017, the following will be delisted: BBR, BITS, C2, CURE, HZ, IOC, MYR, NOBL, NSR, QBK, QORA, QTL, RBY, SDC, UNITY, VOX, XMG"
Most of these coins are far beyond the top-10 cryptocurrencies according to market cap and price, however, and according to reactions on Twitter, traders believe that some of these projects might have pretty good prospects.
However, there are signs that someone knew about Poloniex’s decision to remove some altcoins before the official announcement on Twitter.
Delisting from a major cryptocurrency exchange would have a negative effect on each of the altcoins. Listing and then delisting altcoins will also manipulate markets. But it seems that someone has already earned some money using this situation.
