It looks like all altcoins dump 10-20%. What is the reason? 
I am very sad 
I am very sad Exactly, I also very upset about dumping all Altcoin. So, I wanna ask the same question. Every coin is dumping so low day by day. What's the reason behind it? Already I have losses so much.
Don't worry, let it all drop and take the opportunity to buy some cheap coins over the next couple of weeks. No doomsday scenario here.
