Hello Hello,
time for a serious review. The protagonist:

VieFaucet is a crypto faucet and micro-earning platform that lets users earn small amounts of cryptocurrency. Every activity is paid in tokens.
Exchange rate: 100,000 tokens = 1 USD
Strong Points:
- withdrawal at 0.01$
- faucet amount is decent and claimable every 4 minutes
How can you earn from VieFaucet ?
There are a lot of things going on. But be advised: everything is here but in lilliputian version.
Challenges, daily bonus, level bonus, lottery... are present but the rewards are really tiny
- Faucet: the faucet is actually decent. It pays 65 tokens per claim. Which is relatively high. The interesting part is the time to wait between claims: 4 minutes. Considering theses two factors, I don't know a faucet able to compete in terms of hourly output. The claiming process includes captcha and takes 8-9 clicks in total.
- PTC ads: there a re a lot of ads but very few are decent. At the moment of writing the best is a Bitcotasks' one for 240 tokens followed by another one for 90 tokens. Then few for 50 tokens. After that there are some "must-watch" and a long list of ads paying from 43 to 20 tokens.
- Coupons: three times a day, coupons are distributed on VF Telegram channel. Only 4000 users can get the reward.
- Daily Bonus : a growing bonus from day 1 to day 7, where we get an earning bonus and small amounts of tokens. On day 7, you get 65 tokens + 3% bonus on earnings. To unlock the daily bonus you need to see 2 ads. After day7 the bonus is fixed at 3% until you miss a day.
- Challenges: your activity will bring some bonus tokens. In general the payment is low. The PTC ones are a trap, they force you to see low paying ads. the Faucet's ones are better, they give a bit of value, if you complete them, it's +5 tokens per claim (250 token per 50 claims).
- Leaderboard: the most active users in Offerwall, Referral, PTC, Faucet and Shortlinks can get some nice bonuses. Quite difficult to reach the top but if you can , you will get even 2-3 dollars.
- Lottery: Every day, when you visit your account, you will receive a lottery ticket. The prize is 1,000 tokens. Don't count on it.
- Referrals: you will get 10% of their earnings.
- Levels: activity bring exp, exp increase level. Every day you will receive a bit of token depending on your level (to be confirmed)
- Offerwall: usual stuff, average rewards
- Shortlinks: I honestly skip them, so I can't comment. they pay around 200 tokens so maybe some are worth it.
One issue I encountered is that often the balance for various cryptos is empty and so no withdrawal.
Strategy
I'm still not sure what's the best strategy. The coupons and the Bitcotask ad have good efficiency but alone they bring less than 1 cent.
The daily bonus is just 3% so the effect is limited if you claim just coupons. The faucet pays bad but not horribly, it's barely acceptable, considering you can claim at will. Once you start the faucet claims... well you want to reach the challenge to get an extra +5 tokens. And the Ad for 90 tokens is better than the faucet.
It really depends if you have time/will to do something more rewarding than claiming the faucet. Some days it's nice to have VF Faucet around to claim here and there, some other days there is no time and that's ok too.
Therefore on a perfect day I would get:
50+90+240 tokens (the 90 token ads come up after the morning so I need the 50 one for the bonus; and i need the bonus early because the first coupon is revealed very early in the morning at 4.30 a.m.).
67 tokens for being lvl 34
600 tokens for coupons
1340 or 3348 tokens depending if I do 20 or 50 faucet claims
100 or 250 tokens for challenges
The total amount, once increased by 3% of daily bonus is 2561 or 4784 tokens. we can say between 2 and 5 cents.
In reality, it's a bit of clicking reaching the 20 faucet claim or even worst the 50 claims. I usually get the coupons and the best PTCs. Reaching the Faucet depends on the day.

as you can see no perfect day this week. ;-)
Verdict
VieFaucet is a yes. It's a legit GPT site with a faucet that pays better than others and claimable every 4 minutes.
Worth at least a minimal effort for some PTC and coupons, it's nice to have it around for sinking some faucet claims here and there.
A good support site, considering the 1 cent withdrawal.
