It's one of the common way of earning bitcoin here in bct, it can also help to improve your skill
It's very easy to earn if you have a lot of customers.

there are many way to earn bicoin signayure campaign in which you should easily earn bitcoin . i personally use this campaign. if you have a good mining rig you can mine bitcoin

BTC price reached $2,850 in South Korea yesterday, How great is that? I foresee those individuals holding on to BTC smilling

Ico campaign are paying really good at a moment as if you sell those tokens and convert it to bitcoins then you will see the difference between earning from ico campaign and that from signature campaign as payout are really low at a moment.

... satoshi instead (click-bait master) 

today someone came to me saying how he was regretting not listening to me and investing in bitcoin. apparently he checked the price this morning
and he continued that now it is too late since he can not buy 1 whole bitcoin.

i had to sit him down and have the "talk" with him about all the 8 more zeros that come after the 1 whole bitcoin and the fact that he can choose (almost) any of them and put a number and buy there.

that is why i think it is time to start using the smaller units for bitcoin more often.

i myself prefer Satoshi over all. but there are a lot of them.

most popular:
mBTC= 0.00100000BTC
uBTC=bits= 0.00000100BTC
satoshi=0.00000001BTC

Yes, great for paper wallets.

Faucets + FaucetBOT then maybe there is some point to do this otherwise amounts of satoshi are quite low.

This site https://jochen-hoenicke.de/queue/#2h helps me a lot.

Steps to ensure fastest send.
1. These times you can never be sure of the fees to pay. So I strongly advice that whenever you send, you make sure to opt-in RBF (replace-by-fee) transactions.
2. Go check https://jochen-hoenicke.de/queue/#2h Right now it says there are 1,100 pending TX for 280+ sats per byte.
3. Check https://tradeblock.com/bitcoin/ to find out how much TX was included in the last 4 blocks and when was the last block found.
4. Determine the size of your send by using https://coinb.in/#newTransaction
5. Let's say 382 bytes is the final size of your tx. That's 0.0010696BTC.

From the above steps, you can approximate how much fees to pay.

Bro this is not a site to lure people into a HYIP investment, OP is actually asking a question about earning Bitcoin and you want him to invite on another runaway HYIP site. I know the yields are good and everything but in reality the payment you are getting is from the new members who just joined the program, now with that kind of yield I would say it would not last for a month or so depending on the number of members who are joining that kind of program. I would stay away with that scheme in which there is no guarantee that you will even have your investment back before it runs away.

Recently, I've been trading bitcoins on btc-e, earning only a little, yes, very little, except the fees that btc-e takes.

Besides trading, are there any good method to earn bitcoins?   Thanks.

it is not something you can do after the fact, you should do it before.
for example you shouldn't receive a lot of small transactions like 0.001BTC if it is a service and you are getting paid or withdrawing, then wait until it accumulates to a bigger amount and then request payment.

It's at 450 now but bear in mind this is the estimation to very likely get confirmed in the next block... the median fee is half that and still gets confirmed in hours (yes, I can't believe I'm thinking hours is reasonable now but I actually am getting used to it).

To be fair, my largest txs are all around 250 bytes or so... after learning to keep em small. So I'm still paying a pittance in terms of %.

Core developers must be focused on this issue, 200k unconfirmed transaction base here https://blockchain.info/unconfirmed-transactions is really intimidating.
And maybe before the price reach 2k, the price will be more than 500 satoshis/byte to get faster confirmation. And of course, Fees will be more high and higher until... I don't know what will happen soon.
 

Literally,  bitcoin is money. Therefore you can get bitcoins in the same way you earn money. Any work or job is useful to earn some dollars that you can change for bitcoins later.

Ways to earn bitcoin:
1. trading. you must have special skills to get profit. you must know when the price up and when the price is down
2. join on bounty campaign such as social media campaign. you will get alt coin and you can sell it to get bitcoin
3. signature campaign but your rank must be jr. member or member to join the signature campaign
4. gambling

Just a general reply, once btc fixes its scaling issues there will be billions of ways to earn btc only limited by ones own imagination.

Right now faucets are worthless, and most other free things are worthless unless you are well known, signature campaigns are ok, but generally you have to invest because there is no free lunch.
