Why is moneypot under DDOS attack ?
No one except the DDOSer, probably knows the reason behind the attack. It could be for fun (doubt it), trying to take down a competitor or it is someone who got mad that they lost funds. Could be an extortion attempt as well.
Will this effect investments ?
Yes. Since MoneyPot can't be accessed sometimes, the bankroll won't move during that time, and no profit/loss will happen.
I'm guessing they will pause till everything is under control. But why is this happening ?
It is happening because someone decided to attack moneypot. Read more
here, if your not too busy spamming for YoBit. Maybe after you make your 20 posts?
The attack is to complex/resource intensive for it to be someone doing it for fun. We have received no extortion requests, this is almost certainly a competitor.
