The second reason is link and size. Newbies can only put a tiny message in their signature and they cannot put any link. A user on this forum would have to type the entire website url in their browser (unlikely). Higher ranks can put art and links in their signature.
To get BTC now you have several options:
- Social Media Campaigns (Twitter, Facebook)
- Advertising with Bitcoin Ad Networks
- Trading. Trade with altcoins to bitcoins and vice-versa. This is a challenging way to earn money but you can make 10-50% profits.
- Provide a service on this forum. You can find the link to the service forum here: https://bitcointalk.org/index.php?board=52.0
- Work for $ online and trade for Bitcoin. You can find many websites for work online but many are scam, so go with some big trusted ones. You can easily make $50 a month doing some online work on sites like Amazon MTurk. Trade that money for bitcoins (or goods and sell the goods for bitcoin)
- Work offline (day job) and trade to bitcoin
- Webcam show online (on camsites), trade your earnings for bitcoin
- Faucet if your time is worth nothing
the signature space is restricted by the administration of this forum and the reason is that the newbie do not care for their accounts as it is not a problem or they will not have to wait longer for to get a longer account and with this we can face a lot of spammers . while if someone will do hard work for his account and will wait for longer to get a high rank account and he will know that by breaking the rules he may lose his account so they will care for their accounts.
And the above details lead the campaign managers to restrict newbie from their campaigns.
