These are Jure's words, not mine:
"If you have a full node with NAT TCP port and at least a few 1000 ARCO on it, you are essentially already a master node."
And to be honest, ARCO network looks great!

You want to earn more coins? It's easy! Maybe I should not share this, but I don't care. I currently have about 113,000 ARCO and I'm staking about 300-350 coins/day or ~10k ARCO/month, which at current prices means 0.13 BTC/month. Even 1/15th of these coins can pay the electricity of your PC (if you use one).

If more people have their coins in their wallets, then maybe my personal (and yours) stake will drop, but even 1/3 of this is good enough, no? Master nodes are just a gimmick!
ARCO is currently a pure s*itcoin in terms of usage and we all know this. What is needed is more people involved with ideas (which matters). Don't be fooled by others, were 105 shill accounts are used to "promote" it. You have a fast coin with clean code and people using their real identities. Buy, sell, give advices, promote - there are a lot of opportunities and much space to grow.
