Hi there.
In my opinion, I like Huobi's IEO than Binance's IEO. Right, Binance IEO require the smaller days of holding, but the price of BNB is dumping everyday. But HT isnt, it's price increase everyday, and hard to dump (except BTC dump, all alts will dump). And the Huobi's IEO help us better profit too. From x4-x10 until now, but with Binance's IEO, some IEO is having x0.5-x2 now.
in my opinion about participation in IEO is a personal choice and the matter of rising coin prices from IEO, it depends on the coin project and not from IEO exchange system which is used by the coin, then in my opinion the price of BNB has risen very high and it is natural that now it is time for a correction in the price of BNB, but I'm sure that soon the price of BNB will start to rise again and of course it will give a very big profit for people who invest in BNB, then I personally prefer to participate in Binance IEO, because in my opinion Binance exchange is the most popular exchange and of course has a very high volume, so when I participate in Binance IEO, then it must be very easy for me to sell the coin.
