I was wondering if there is a cap to the profit one can make on Freebitco.in, for example with multipy btc or betting.
The only profit cap I'm aware of in the whole site is the 20
BTC MAX profit per Hi-Lo (Multiply) bet. That means that if you wager 10
BTC at x2 odds, or 15
BTC at those same x2 odds, you'll only win 20
BTC in the event of winning. There's no limit I'm aware of in betting. Furthermore, both betting and Multiply games are encouraged, both by daily jackpots and monthly competitions (biggest bettors win those).
The same question can be asked in a different way, i.e. is there a cap to withdrawals on Freebitco.in?
I've been using the site for almost 4 years, and there is no withdrawal limit.
There are a couple of things that you can't do (faucet abuse) and that will lead to your account being blacklisted and unable to withdraw, but that's another thing, not a restriction per se. Some of those behaviours include using bots to claim the hourly faucet, multi accounts, ...
If you still have doubts about it, you can ask them both on the
Gambling and on the
Micro-Earnings threads they have, and TheQuinn will answer you whenever he is able to do so. I'd suggest you locked this topic now, to prevent further bumping it (lock topix should appear on the lower left of your screen).
