Is it possible to blackhat now to get future results ?

I was stupid enough to buy many domain names, now knowing that only a few i can actually use to start with for some WH niche and I want to focus my time on developing those first.

In between there are 2 domains relating to the financial sector ( different keyword ) but as I see it now there are just way to many competitors. I downloaded Traffic Travis 3 from BHW and according to it 1 of them has a SEC of 145 mil in G and 835 mil in Y and an Extremely Difficult rating. The other one results in a SEC of 31 mil in G and 332 in Y also Extremely Difficult rating.

I rather spend my time on developing the use full domains i have in WH then spend all my time on 2 domains for a whole year and probably ending without result.

So my question is, is it possible and what are the risks if i start working on those 2 hard domains with BH ? I am thinking of adding articles to the 2 websites, article spinning, submitting, link building etc.
Is it use full to do this for 6 months to a year ? During this period not trying to make money so not getting banned from any future moneymakers.

I read a lot about sandboxing but i could not find a post about what it meant and future problems can be except being not ranked for a few months. That the sites will not be ranked for a while is not a problem, will all the work which is done through BH be any value after this sandbox period ?

I hope that i could explain good enough what i mean and wait your comment with eager.

You can always create a basic site on these domains, totally WH and leave them.
After a few years you will have a few aged, trusted domains, good for SEO or selling.

The domain names are not strong enough to sell for any decent profit even if aged, might be worth something if they would get organic traffic but also i do not see that happening WH without some major work .

I see that a lot of people a reading this thread so i presume there are more people who are interested to know about it.

I am sure there are many experienced IM's here who either tried this or have a vision about it. Please collaborate on this subject as of right now i intend to start with this project which i think will take a year and i hate to see in the end that i wasted my time and resources to something which possible won't work at all.

This is the best way to "See" things. Vision is First. I understand your desire to buy so many domains - get the name before someone else gets it! You are not the first. Many still are doing that. One of my first clients spent a year buying domains hoping to 'get rich' off the names. I did it too back in the day. It is not a stupid thing. You may just be a talented visionary. You may be way ahead of your time on some things. In most cases your question is the answer. For instance with clear vision you won't need to blackhat as your future results will depend upon visualizing clearly. Think about concept models. We'll start with a concept car. Think of your domain name like that. Brainstorm scenarios of possible use. Pay close attention to what you see because being ahead of your time happens a lot. Sometimes we look at history and see inventors and think wow what if I can come up with a brillant idea for something new. Think wider than just the "Domain Name" and ask yourself what if I only had a newsletter called "same name as domain" what would it be like, WHo would subscribe to it? and why?. Think about mobile and tablet outlooks with regards to your domain. For Brainstorming & feedback scan existing forums & blogs regarding each of your domains with the goal of getting feedback. Your goal should be that of gaining clarity. All of your domains are like seeds. So as a gardener your thoughts must also go towards the soil. When I first stepped into the webdesign arena I was hard pressed that Macromedia Flash was going to be my ticket and I did so many flash bang wow sites and now I get no request for flash sites but lots of request for mobile and tablet yet I held on hoping for Flash on tablets - which is a current slow go almost no. So since I still love animation and special effects bang pow and wow I moved to after effects and video intros, in which case youtube came along and her clones daily motion, vimeo etc etc etc and as i still observe new types of sites come and evolve to greatness (Facebook, Twitter, Linkedin, Pinterest) I now use a paired approach (Fighter and Wingman) to determine the sequence of where to focus attention and energy. By using this approach I am way more confident in research and vision. I wouldn't even think about sandboxing I would do as you have said Article , submit and link building and add video and pinterest for capturing the Serps then expand and connect from there. Layout your plans in a mindmap tool like xmind or freemind so you can see where to group and expand. If you are in the financial sector because of previous knowledge or special training you may need to boost your clarity and confidence by writing an ebook about the domain subject you are most passionate about and selling it at a low cost on the warrior forum and/or JVzoo the Chapters and content can come from your mindmap. You can then use this to build your list. Always challenge yourself by setting weekly, monthly goals to complete certain task.
