I am learning about altcoins issued through IEO because these are altcoins supported by the exchange that released it. Currently, I only choose ONE, BTT because these are 2 altcoins issued through Binance, and this is the leading exchange in the world. The level of its influence is bringing a lot of benefits to me with a fixed profit of 5-10% weekly. You can learn about ONE and BTT if you are interested in this.
