It was only 1000% for the first 100 masternodes online based on the ICO price. If you read the whole ANN thread you would realise that straight away.
If you look at what a masternode ROI is you will understand. It depends on the masternode count and the % of block reward distributed to the masternode holders.
If a coin has badly calculated specifications the ROI will decrease dramatically. But if the specifications are good like a low max coin total and a high masternode collateral you have a unique situation. This leads to more of a percentage of the total coins in circulation being locked in masternodes which lessens the circulating supply further.
If you look at DASH, they have about 18.9million max supply of coins, and a current circulation of 7.74million. They have a 1000 coin masternode collateral so with 4759 masternodes currently online that is 4,759,000 coins locked out of the current supply of 7.74 million.
I personally invested in Tokugawa coin for the specifications of the coin. With 20mill max supply and a higher 2500 coin masternode collateral. I am not saying Tokugawa coin is like DASH, but I'm saying you need to understand what masternode ROI is.
If a coin's price builds at the same rate at the masternode count the ROI does not change.
If a coins price builds at the same rate as the masternode count there is also a point where the masternode count slows down its increase as the collateral coins cost too much to buy a masternode. ROI has many moving parts to understand.
With good community support and marketing Tokugawa coin can be a great investment. Not only for masternode holders, but for people to just stake.
This depends on the developer. He did say he is friends with the XUV coin developer. This doesn't concern me, I invested in Bitcloud and those Devs run Bitsend and Bitcore, 3 great projects.
What I look for after coin specifications is the developers productivity. Now you have to give a new project the benefit of the doubt. And so far he has listed on Cryptopia even before he said he would. I checked the wallet and set up a masternode and it worked fine. I have seen he also added Tokugawa to Blockfolio, as I use this app to monitor my portfolio, its great. Now he works on Qryptos and the Android wallet.
If you need some one to spell it out for you, there is some important things to look for in a coin. And of course through all this I only invest what I can afford to loose.
