these things seems waste of time for me. instead of hoping to won some coins from this system airdrop is better.
I don't think so. There are a lot of complaints about airdrops too. On FreeBitco.in, on the other hand, it's not $0.002 worth of BTC every hour which is attractive. Spending very little time for visiting the site you have a chance to win $20 or even $200 while risking nothing, and that's what is engaging. Also it is important to note that they pay their winners regularly unlike many other sites who only promise big prizes but then don't pay out.
Don't forget about lottery! there's also a chance of winning huge jackpot/prize from lottery, everyone gets 2 free tickets on each faucet claim. some have won lottery with less than 10 tickets, you never know when you can get lucky.
not a time waste for me(i do it in free time).
Actually I disabled lottery some time ago to receive reward points instead of lottery tickets. I tried to win in the lottery many times before that decision, I even was buying tickets several times but then I gave up.
The reward points are good thing though. You can redeem them to increase your minimum free BTC reward up to 1000% for 24 hours after redemption.
I've got a few more details about the reduced awards algorithm I can share with you.
The algorithm for reducing rewards takes a combination of the balance, wager, lottery and jackpot spending to calculate the reward. Jackpot spending has a higher weight (4x) and the lottery has the highest weight (20x).
If you do not want to gamble you can keep a balance above $50 to not have reduced rewards.
Most users will not need to keep the full balance though because their gambling history is also added up to calculate.
New accounts have full rewards for the first 100 rolls to help them build up a history and then the algorithm is applied to them. So opening a new account might seem like it helps but it won't.
Additionally, the balance needed to have no captcha is $100.
Thank you! Yesterday I was going to tell that my free play rewards weren't reduced but then I thought that it may disclose the specifics of the algorithm
and I restrained myself from posting that info. So, I'm happy to confirm that I have the same rewards as before.
