A few newbie questions (Dash is attracting attention...):

1) To run a masternode, besides having 1k dash in a wallet, do I need a computer working 24/7? What happens if there is a downtime (let's say I run out of power, my ISP is down, or whatever...)? Do I lose rewards for that month?
==>Reward frequency depends on total number of MN (~4000 now is around 1 payment every week)
Yes if your daemon go offline more than ~70minutes, yes you'll lose your position in the queue payment, and will have to wait ~7days


2) If I run a masternode on my computer with 2k dash, do I get twice the reward? Or do I need to have 2 wallets and 2 computers to earn twice what I could earn with 1k dash in a masternode? Or one wallet with 2 computers?
==>Yes need two wallets (can be merge in one, but need two payment TX of 1K each) and two computer

I hope the answer helps other people interested.

Thanks!
