Nope, 30k satoshi account balance won't remove such restrictions. We were required to have at least $100 in BTC to remove the captcha restriction on our account. If I'm not wrong, then keeping such amount of BTC doesn't work anymore to remove the captcha. Only wagering and buying lottery tickets can fix the base reward amount. I could be wrong though, you may verify it by keeping $100 in BTC to your account.
If you don't have $100 in BTC saved on the site, your base reward in the freeroll will be less than the current 2 satoshis, but if you have more than $100 in BTC stored on the site, you will receive 2 sats in the freeroll, and if you bet a lot and buy a lot of lottery tickets, your base reward will increase, but definitely not. ... also, having more than 100$ in BTC on the site, also unlocks the reward bonuses that you can activate for 24 hours in the Rewards section
