In my opinion you should immediately start selling coins or people will leave this project. A lot of people are interested in this however without frequent updates the interest will fall down.
it would be nice but Bittrex has this rule. in this case i think it's good because of the holidays. A lot of ppl are waiting for this coin to go live
rule that says you can't sell coin on your site after IPO?
there is no such rules. Nothing was stopping OP from holding some share of his own coin and sell it on his site as soon as IPO was done to make sure that price stays stable. The fact that he didn't do it and the fact that 80 BTC worth of NOO were bought at the end moment of ICO is red flagging to me.
Now, I'm pretty sure that those 80 BTC were bought by Noo but that wouldn't matter if the goal is to turn this into something else and not just p&d.
122 coins sold during ICO
100 BTC was minimum or trex would refund BTC to users
80 BTC were bought at last moment
122-80=42 BTC profit
If 80 BTC weren't spent during last moment (which would be returned to Noo after IPO) then OP would be missing out on 42 BTC profit. It makes sense for him to buy all those coins so he could get the profit of 42 BTC. It seems like if you're holding 100+ BTC then IPO is the only way you can make big money in crypto. Most coins barely have any volume to spend that much BTC at one time. T h i n k.
In any IPO. Any coin that hits its minimum when it's about to get closed is a HUGE red flag. I'm surprised investors can't see it because they're blind folded by how price would pump after IPO. In fact..I can write it down for you that price would dump like crazy as soon as trading goes live..that's when I would jump in to buy or not..depends on the news
