I think you should buy coins for exchanges. now many IEO projects are being implemented and the coins of exchanges are being welcomed by many investors. Big exchanges like BNB, Huobi, Okex, Bibox, are being bought and hold by investors. surely its price will increase from 20-25%.
This is the great revival most of us have been waiting for and for now, it is really working and building lots of confidence of investors back with the projects being funded through exchanges IEO.
Most of these coins started showing signs of increase the moment they are launched and bought but I don’t think we have so many projects being listed because I can only count four that Binance being the biggest exchange has already carried out successfully, though I have not checked other exchanges you have mention, Binance is the major exchanges I have been using from onset for my exchanges and holdings.
It is better to commit funds in these exchanges IEO than short selling.
