I only know coinomi since I have never try any wallet like that which provide more different altcoins to store. I just wondering why I need an altcoin online wallet if I just want to keep them for short time. I will use an exchange to store my 10 different altcoins if I use it for just make short profit. But if I want to keep it for more than a year, I will use an offline wallet for safety.
Really? Will that be a wise thing storing one's coins on an exchange? Considering the fact that some of these exchanges reported that they were hacked in the past and no coins returned to investors. Don't you think this decision of yours may backfire on you?
