I ever saw someone say it in this forum, but if you have an account Sr.member above and join the signature campaign + trade was easy to make 1 BTC in one month.
This is false you will not make a 1 BTC per month through sigature campaigns. There are some like mod's or some user a campaign will pay more for. Here is kinda the page to look for payment -
https://bitcointalk.org/index.php?topic=615953.0 . So the best are mid .30 or so. So that leaves a LOT to earn from trading.
I do not think you can take mid .30's each month and consistently change it to 1 BTC a month. Yes you can make a nice amout of extra money but day's of 1 BTC per month from sig campaigns are just long gone. BTC value has went up to a point where they just can't pay that 1 BTC per month per user.
Yes, some members can make 1 BTC a month. But in order to do it, the best way (in my opinion) is to find a job that pays ~20 USD a day.
yeah but in vietnam 20 USD /day is a problem if you wanted to get 20 USD in a day, you could have a job like manager in hotel, work in a office,...
but i am just a kid and i am 16 years old how to can i get this job
Not sure how it is in Vietnam just as I am not familiar with local working laws. But in US at 16 you can work I believe without restrictions, at 14-16 I believe they are way's to work but laws to follow as a minor. But a lot of 16 year old's can get job's and buy coins with it. Granted not all jobs some require higher ages like those selling alcohol or firearms for example. But in US a lot of jobs are open to 16 at least legally.
