I sold all mine in June at around $2,300. The bubble is deflating look out below.. Fun ride but I am out until prices stabilize, I might buy back in at triple digits. 

Sure sign of a bubble - 1- Everyone is buying on pure speculation Bennie Babies, extra houses and condos in the 2008 housing bubble, Tulips, etc "just buy it will always be worth more." 
2- Look at the charts, pure spike. That is not sustainable..

No one is actually using Bitcions in a mainstream use. People have to jump tru hoops just to buy a trinket on line. No one is storing wealth in it because it is to unstable and new.

Pure Speculation=Pure Bubble

You are buying on a spike/peak. When you make speculative buys the main strategy is to buy low sell high. You are buying high and .... most a speculation a low in the next few weeks.

I am sure many bullish people on here will tell you it will go up, up,, but other will tell you they are waiting for a crash.  Never know in the world of speculative investments.

Those are usually free. Here is one- https://www.google.com/intl/en_us/ads/adwords-coupon.html

You can send me some Bitcion for it if you like

You need targeted audience. When most people go on social media they are looking for social interaction, they are not looking to invest in some strange digital currency they do not even understand. and they are not there to take lessons and be educated on it. They want to see train-wreak cousin sally make drunken posts or look for cooking recipes.

People market on social media because it is easy and it is usually a fruitless time suck.

IMO the best way to promote products or links is to provide valuable information to viewers-Quality web pages, blog post, podcasts. When you provide quality information you are also showing your self as an expert in the field=gaining trust and you are dealing with a targeted audience that is already looking to research and buy.

I have been helping people with their internet marketing for about 15 years. A couple of things I have noticed.

- The more competitive the field is the more work and harder it will be. Ranking in competitive fields=money. You do not take over flows of money by tossing some SEO guy $99. It is just not that easy.

- Internet marketing starts before you build your site. You domain, keywords, layout structure all need to be built around your marketing intentions and goals. A lot of people toss up a site then contact a marking person and say "I need to rank" Rank in what..? or "I need traffic" Traffic from where ? These types of things need to be discussed and planed before the site gets laid out.

- You need to know the field and your customers you are marketing in. Who are you trying to get to your site ? How are they going to find you ? What do the need ? What do they want ? Why do they want your ___ ?

There is a lot of dimensions in internet marking that need to come together to make stuff happen. On site seo, site layout, site design, market positioning, etc.
