Can you stake? Is there a masternode? What are the benefits of the platform and for the investor in the currency?
Yes - If you've used Dash or PIVX, you will know all about the joys of staking and hosting a masternode. Basically, it turns your wallet into a savings account, which generates interest on a daily basis. With Dash trading at $238ish, you'll need to commit about $238,000 to host a masternode on that that network. With TokenStub starting out at $0.10, it would cost you $10,000 to host a masternode.
From Dash's dedicated masternode site:INVESTING IN A MASTERNODE CAN SOMETIMES BE A LITTLE CONFUSING SO HERES THE ANALOGY
Think of a masternode as a savings account with a minimum deposit of 1,000 DASH. A traditional savings account pays interest, and a masternode pays rewards which are very much like interest. In the case of a masternode, the reward (or interest) comes from performing services for the network. Not from lending.
The big difference between a traditional savings account and a masternode is that your initial deposit never leaves your possession.
