Somehow I managed to stake before to hard fork, to be exact, 20 times. With the hard fork am I going to lose my 20x that I built before?
I am asking this because I got a 0 reward stake from experimental build. Which shows Turbo: 0x.
Your multiplier only looks at the last 48 hours, it doesn't stack up. So if all your stakes were over 48 hours ago, your multiplier will be back at 0. I think it was a minor oversight because it appears the multiplier starts at 0 for first stake, 1 for 2nd, 2 for 3rd, and so on. So you effectively need to stake 3 blocks before you get to at least 2x and the multiplier takes effect.
If you are asking if the 0 multiplier multiplies your reward by 0, thereby giving you a 0 reward, no it doesn't. You still get your standard stake reward.
Well, that sucks to be honest. It would only award big wallets therefore your idea of fair distrubition through staking seems not possible.
SockPuppet is trying to help, but his explanation is a little inaccurate.
The network rejects any 0 PoS block reward and therefore any 0 multiplier. You start at 1, not 0, in all cases. I actually put out an "experimental" release yesterday allowing users to submit 0 block rewards, but as a lot of people experienced, it played havoc with the network because 0 block rewards were rejected by non-experimental clients, even if they didn't mint the block themselves.
Finally, in terms of fair distribution, we don't know how Turbo Stake will play out. Cryptocurrencies are by nature experimental, especially alt coins that want to break new ground. Let's see what happens with Turbo Stake. In the end, I believe the most dedicated stakers will win, whether they start small or not. This isn't all luck. Staking and supporting the network requires effort, especially early in the life of a PoW/PoS hybrid. We hope Turbo Stake will appropriately reward this effort.
I figured the multiplier started out at 0 because as you can see, my first 2 stakes were both 1x. I assumed behind the scenes it counted your first 2 stakes as 0 and 1, but effectively rewarded them both as 1x.
