No. HEX doesn't have an owner either. Richard Heart is the founder of HEX, but it is a fully decentralised product on the blockchain.
Nowhere. HEX isn't a project. It's a completed product and has been working flawlessly for over 1,5 year right now.
At present, HEX offers a 38% interest rate, but some may question its sustainability. Similar to the euro, HEX experiences inflation, with its annual percentage yield (APY) ranging from 3.69% to 369%. The euro's inflation rate averages around 6% annually, which reduces the purchasing power of each euro as more are added. Unfortunately, these newly created euros rarely end up in the hands of the public, instead being held by the government, banks, and other entities.  

HEX differs from the euro in that its inflation rate is and will remain at 3.69% annually. The exciting part about HEX is that it is distributed among stakers - individuals who have locked their HEX for a specific period. The longer and more HEX you lock, the greater the percentage of that 3.69% you will receive. If 1% of all HEX is locked, stakers will earn a 369% APY, while 10% and 100% lockups yield 36.9% and 3.69%, respectively. Thus, your earnings are dependent on the amount of locked HEX.

When you lock your HEX, the HEX gets replaced by Shares. The number of Shares you receive depends on two factors:

1) The amount of HEX you're locking up - the more HEX you lock up, the more Shares you receive.
2) The length of the lock-up period - the longer you lock up your HEX, the more Shares you receive. You might come across the terms T-shares (trillion shares) and B-shares (billion shares) in discussions. You can also monitor your accumulated interest in the StakerApp.

Once the lock-up period ends, you can claim your rewards. After that, you can either hold onto your rewards in your wallet, sell them or even lock them up again!
Absolutely not. Since its launch, HEX's price has increased significantly. If you had simply bought HEX and held onto it in your wallet, your investment would have potentially increased by 10,000 times. The beauty of HEX is that if you had chosen to lock it up, you would have earned an additional 38% APY.
You can lock it up for a minimum of 1 day, and a maximum of 5555 days.
When you lock up your HEX for a specific period, you receive shares. The longer you lock up your HEX, the more Shares you get. Shares are the main element of HEX as they determine the amount of interest you'll receive on your investment. You'll often hear people referring to T-shares, which represent a trillion shares, and B-shares, which represent one billion shares.
The decision to stake your HEX for a particular duration is a personal one, and it's best to make it based on your own goals and preferences. If you want to earn as much interest as possible, it's advisable to stake your HEX for the longest period possible, as this will result in a higher number of shares. In my case, I use a staking ladder strategy as my preferred method.
To implement a staking ladder strategy, you would set up multiple lock-ups with varying durations that end at regular intervals, such as every 3, 6, or 12 months, over a period of 15 years.

While staking for the maximum duration of 5555 days will yield the most shares and interest, waiting for 15 years may not be desirable for some investors. By breaking up the lock-ups and staggering their end dates, you can benefit from the higher interest on the longer durations while also receiving income from the shorter durations throughout the 15-year period.
No. When you place a stake you have until the end of the day to cancel it. When the day ends (depending on the time zone) your stake has started and you can no longer cancel it.
Yes, it is possible to end your lock-up early, but there will be a penalty fee for doing so. The amount of the penalty depends on several factors, such as how much time is left on your lock-up period. To find out how big the penalty would be for ending your stake early, it's recommended to consult the StakerApp.
