one of the most favorite altcoin for me is bitxoxo though it was still on ICO but still i find it as the best altcoin for me , simply because bitxoxo is the top trading platform in india for 2 years already they are open for suggestion to improve the trading platform more . now their ICO are receiving lots of support worldwide . I alwasys wish for the best of their ICO since they have the 100m$ total volumes trades in a day
