I tried this faucet and I couldn't make anything from this.
Still I see that this thread is very active and I wonder if you are making any money from it.
Which is the best strategy to follow in order to accumulate some BTC?
The best way to make freebtc profitable is to use points to redeem bonuses (I call them "boosters") especially if you don't have a lot o referrals.
Sorry to the forum staff if I am crossposting...
1) be sure to avoid limitations for a long time. Using lottery and hi-low doesn't mean that an account will be not afflicted by limitations in future, the only way is to have AT LEAST $50 in the balance, better if more than that (btc value can change a lot...). Better if balance is over $100 to also avoid captcha and, of course, getting more interests.
2) do not activate btc boosters without point boosters. If you redeem a btc booster you have to do more claims you can, there is no sense in not redeeming also a point booster because you need points to redeem next boosters in future. It's possible to redeem 1 booster for each kind (1points+1btc+1lottery, if you are intrested in lottery) but not 2 of the same kind.
3) be sure to be able to claim AT LEAST 12times during points boosters activation. This one you already know, and all points boosters have the same ratio (they always cost 12times what they give per single claim).
4) btc boosters have a different gaining "range" based on the minimum prize. They are really profitable when the minimum prize is 16-30sat or 46-60sat or 76-90sat etc. and they are not when the minimum is 1-15sat or 31-45sat etc. In fact if claim is on "the second half of 30sat minimum prize" they are in the most profitable range, that means you need less claims to get back points used redeeming them, the more close to 30-60-90-etc. is the minimum the more you gain.
5) use a timer to remind when its time to claim. I can assure you, it takes less than 30seconds to open the cell browser, do a claim and set timer again, less than to reply to a sms/whatsapp. 59:30 is the best setting.
6) use a smartphone to do claims. Even if you live in front of your pc using a mobile device allows you to claim when/where you want.
