Nice concept for better adoption of bitcoin however i am in Asian country so it is not possible for me to buy and use these cards here. But soon i gonna be in USA for my further studies, will keep an eye on your service when i will be there.

If you generate that vanity address from your own computer and paper wallet in offline mode than it may be considered safe from my prospective. If you really care about price crashing than you can also have one copy of that paper wallet with you to sell. And also laminating that paper and putting it in safe box before giving her may protect paper from damaging on long year of storage.

Actually bitcoin is not run by a foundation or company so i dont think there will be any rich guy who just like to spend few hundreds just to promote bitcoin. You can see lots of bitcoin service related ads running in youtube but never seen ads just to promote what bitcoin is.

Currently etherum is messed up with the hard fork creating another eth clone named etc. And also DAO was the token distributed on ethereum chain which got drained away from the hacker due to security flaw in dao. And this is the actual reason for why they have done hard fork, it is still under early phase of adoption and testing but have smart contract feature which bitcoin dont have however bitcoin seems superior to me to be used in daily life as secure payment processor.

Almost all casino sites pay referral commision when your refered person/friend play games there but i don't think there are any which gives you commision if you brought them investor who like to invest in their bankroll as there is always option for investor to divest whenver he like so giving commision on investment may create abuse to whole referral system or there may be other reasons for why they don't give this.

I like the concept but actually if those bitcoins are not a real bitcoin why to have account registered just to play. If you can add auto account generation system in your dice script just like few new dice site do, it will be nice.

Faucet is actually not profitable these days for sure, but if any faucet manage to gather lots of unique traffic per day than they may manage to get few bitcoin through ads after even paying to all their members. But bots came in between or even in early stages of  faucet and drained out all satoshi from it (when using faucetbox) and people really don't love directly manually paying faucets these days as they all want instant payment. And also it is quite tedious for owners to do all payments manually.

Concept seems nice and also script to fetch ebay bitcoin related listing seems working however you need to work on site design and also heavily on your homepage to include few ebay listing as well as news/blogs on first look.

I was searching for api of your to be used for auto shortening link which i couldn't find in your site, found this one http://shamp.ooo/bookmarklet.html
but this need manual work to post directly in twitter. Have you planned of adding such type of api just like coinurl to automate the shortening process?

Actually i have also heard that, but i am still in the way to finish MR. robot season 1. I started it quite late after some friend of mine mentioned it is related to encryption, bitcoin and hacker.

Talking about this startup series i started today but it kinda boring to me not much action, will wait till episode 2. May be that will be little more spicy...

Anything stored online are vulnerable to hack or steal of data and also trusting third party to do so is more riskier. Just putting bitcoin paper wallet generated offline in a safe place in your home or even in a hole putting those paper wallet in a glass bottle could be considered good way to store private keys. Even authorities may not find those grounded private keys in worst case.

Just another ponzi popped up, better to stay away. Password protected site for private investors only , bank mining bitcoin for us? 
Really a funny way to introduce another cloud mining ponzi which even don't have encryption.

I think all are needed and are present in most of the dice sites running right now. Other than this i think dice site also have to optimize their script for fast rolling as well as autobet without any time lagging. And also moderator team always available on chat for support as well as having good support team behind to help with support ticket within few hours.

Gambling can sometime become addiction if the one who keep on playing doubling his betting on every loss he make. If you keep on winning for few times, you try to start playing with bigger size bets and soon loss all you have than to get those you have lost you even make bet bigger and loss more than what you have actually won before. So this keep on going untill ending up with no any left in hand to gamble.

No bro take this as lesson learned for your life not to gamble again, i am quite confident that you have enough talent and capabilities to earn more than what you lost in coming future. However i know how it feels lossing hard earned money in few hours, i have also lost big few years back in gambling. DOn't be sad trust on yourself bright future is ahead, sorry for your loss.

Nice amount of free satoshi to try with, i get 4000 satoshi but won at first claim but loss with 8000 satoshi bet. My bad luck, will try after one day, the script look known to me used in several casinos.

I don't think what they offer is real, never heard about them but i know little about double spending. They have also not explain clearly what they actually offer. Even with double spending only one transaction will be confirmed so getting same bitcoin in two addresses is not real. Most of the services wait till transaction get confirmed or check atleast priority of transaction according to transaction fee used before confirming any payment to them.

I think this could be scam attempt.

Thanks for sharing link, i know 123movies from a long time and basically watched several series their, watching jason bourne right now. I gonna watch this series before bourne. 

I think your third idea could be success and may also not require a lot of seed money to start with, both ideas of opening trading site, lending site will require a big team as well as huge seed money. And also don't forget the headache you have to keep about security and market competition/promotion.

Site look clean and good but rather than using php codes to calculate price here http://www.bitcoin-price.live/usd_btc.php
you could have used java making it responsive, loading whole page to just see results doesn't make much sense these days.
