it goes fast in the beginning but at the end it takes very long because you get a lot of empty boxes and small amounts of bitcoin. I'm on level 5 a long time but still have reached 73% of the minimum withdraw amount.

There are tons of clues its fake:
1. terms say at point 2 its an online based game
2. terms say at point 8 theres no monetary value
3. terms say they can nullify your stats at any time
4. no vpn detection. You can fake easily invites by changing the ip. I tried it. Made 87 invites with random names and emails got country bonus, registration and clicking on link - tons of gems and xp - lvl 5 portal box in under 1 hour
5. scam advising sites call it scam
6. Detection of adblock+ but no detection of other uncommon adblockers
7. whois domain resolve says lootbits is a whoisguard protected site. No information about owners. Every serious company doesnt need a whois protection
8. 0.049 btc for dumb riskfree tapping on boxes REALLY WTF?!?! ARE YOU FU**IN SERIOUS?!?!
