There are many ways to get bitcoin in addition to mine, we can look for bitcoin in a free way that is with faucets or with bounty that is short term.

Faucet is the most fitted on what you are looking for. This is classic method yet effective especially for newbie that want bitcoin easily. You can also join Bounty Campaign on altcoin section, You can use there your social media. Just follow their requirements and instructions then you will have money, NOT daily but the amount of profit is good.

If you talking very little amount, then faucet or doing some survey it suitable for you. Just to increase your income, try to find a lot people that will register under your referral. If you're too lazy to do faucet, then you must try to join an ico, even it isn't bitcoin but still worth it to try. Another way is gambling and do some freelance.

A lot of people are advising you to start faucetting, however, i'd strongly advise against this.
I haven't touched faucets in a very long time, but after googling for about 2 minutes, i can conclude that the average claim is less than 100 sat... Even if you use a semi-automatic script, i would find it very supprising if you were able to claim more than 60 times/hour, making your average income about 6000 sat/hour...
That's about 50 dollarcents for an hour of clicking and solving captcha's.

I don't know where you're from, but in my country, the minimum wage is something like 7 or 8 euro's/hour... If you work at McDonalds, you'll be able to buy 14-16 times as much BTC with your wage compared to the amount you get by faucetting.

So, if you want my advice on how to get small amounts of BTC on a daily basis: if you don't have very specific online skills, you're probably better off getting an IRL job, and convert a couple of bucks from your wage in BTC on a daily/weekly/monthly basis, then keep this BTC for potential future price rises.

If you only want a very tiny amount then you can go with faucets. That's the first way that I have think by reading what you are looking for. You can claim those small amount of mbtc and after that you can use it wherever you want, cash it out, store it and keep it until you can have a minimal amount to invest into trading.

Its depends on your budget and your time. If you have big budget and lots of free time i recomend for mining or invest. If you have low budget but have lots of free time, you can choose faucet method.  whatever method you do it will be profitable, if you do it well.

we have different faucets here in crypto you can earn there a little but i think spend your time there a little then better to do is keep reading different topics here in forum because the earning here is base on your knowledge and i think for more good better to do trading like study here in crypto another thing you can see in trading that all coins are moving go low and high so you can earn by that if you know what can happen to a coin so always monitor that then do faucets

You may join campaigns in order for you to earn. The higher the position, the higher the wage you can get. Joining campaign is so easy and through that, you can earn big or a lot of bitcoin weekly. But you should post ideas that are full of sense so others may learn too.
