Altough, theoretically, most of your points are correct, i would still like to add some remarks to each of the points you raise:
1. Faucet
You can get any coin with claim it every 1 hour,1minute or no waiting time. Like freebitco.in and freedoge.co.in or Faucethub.
Altough i haven't tested out a faucet in years, i quickly browsed to faucethub and found the average claim seems to be around ~100sat nowadays (i did not do the math, i just looked at the list and remember that most faucets don't actually give you the amounts they claim in those toplists).
I remember that due to the hidden links, captcha's, popups, fake faucets, dry faucets,... It would be a miracle if you were able to claim more than 50 faucets per hour.
This would make your average "income" 5000 sat/hour... That's about 18 cents/hour. In my country, the minimum income (after taxing) is about 7€/hour.
Working on an assambly line or at Mcdonalds would be about 40 times more efficient than claiming from faucets. Next to this, working at a factory or a fastfood joint wouldn't require you to invest in a pc, electricity, internet,... It would also give you access to social benefits like insurance, and you would actually contribute to the growth of your country.
My advice: get a real job, buy BTC with part of your wage... Far more efficient
2. Airdrops
Its just like a giveaway to user who participate in their project. Blockchain give free XLM to their member who has tier 2 in their profile and some ICO creating airdrop to introduce their project.
They give 25 XLM AFTER you gave them your name, address, phone number, copy of your ID... My privacy is worth more than 25 XLM (less than €2)
3. Cloud Mining
Mining in website like EOBOT. You can claim GHS everyday to increase your speed mining in EOBOT.
There are only 2 types of cloudmining companies:
- 99,9% are scams
- 0.1% are companies that sell you 100% of their risk for a very, very, very small part of the potential profits
The 99,9% and 0.1% statistics are not a result of an actual calculation... They are a result of my experience within this comunity and are more of a gut feeling instead of a "calculated" result. My gut feeling actually tells me that the 99,9% is actually an under-estimation.
4. Advertise
If you have website with good visitors, you can advertise your website with A-ADS. you can get bitcoin if your visitors click your ads.
Sure, i run a-ads on my sites to... But you'd need a site that gets thousands of unique visitors a day to make peanuts... I've been able to claim from them ONCE, and i run sites that do receive a couple hundred uniques a day for a couple of years now
5. Social Media
You can earn by posting any Story in Belacam. If other member like your post, you can get free coin.
Don't know this technique, but be carefull not to promote scams while posting things on social media!!!
There are many more ways to earn free cryptocurrency to share in here. like a Bounty, View Ads, Take a Survey, Play a Games, Gambling and many more.
Bounty = a type of promotion that decreases everybody's bitcointalk experience IMHO. If you do bounty reports on bitcointalk, don't expect any respected member to take you seriously ever again
View Ads = very low hourly income, get a IRL job instead
Take a Survey = very low hourly income, get a IRL job instead
Play a Games = very low hourly income, get a IRL job instead
Gambling = bad advice... The house always wins. Sure, you can get lucky once in a while, but on average, the total group of players will always lose more than they win (and in the odd case the group of players wins more than they lose, the casino goes bancrupt and dissapears)
