We currently offer Bitcoin withdrawals and deposits on our website. Blockchain API is used to handle all operations.
Only problem is Blockchain Receive API's 20 address gap limit, as mentioned here: http://bitcoinx.io/news/articles/blockchain-info-updates-receive-payments-api-version-to-address-edge-cases/
Now we get a lot of curious users who click on Bitcoin deposit button and commit to it without actually sending any transaction, which easily build up to 20 addresses. What are some ways of removing this limitation? I have few ideas but they are rather bulky and some require complete re-write of code and replacement of Blockchain API. Can you guys offer any insight and/or advice? How can this problem be solved in elegant and efficient way?

I need to get some Western Union money urgently and I'm willing to sell my Bitcoins for it.
I already posted in Currency Exchange but no one replied even though I made a generous offer. (Other than scammers)

Is there any service that can get me WU in maximum of 2-3 days?

I found out about unichange.me but I'm not sure if I can trust them.
Can I trust them with like $100 of Bitcoin?

Just updated amount from $80 to $85.

I'll give you 85USD in Bitcoin.
You'll send me 70USD through Western Union. (Deduct WU fees from $70)
You get to keep $15.

Don't PM me unless you have reputation.
I'll ignore you if you don't have reputation.

I'm willing to sell my $65 in BTC for $60 AirBnB Gift Card.

You can purchase the gift card with your credit/debit card here: https://www.airbnb.com/gift/send
Card is virtual, it's not physical delivery.
You need to be an USA resident to be able to purchase the card. Or simply own an USA debit/credit card. (Not sure which)

Only contact me if you are trusted. I will ignore your PM if you don't have reputation somewhere.
Don't post in the thread - I will not check. PM me instead.

I remember seeing AdWords credits and Facebook Ad credits around in this forum and other forums like Hackforums.net
They are usually extremely cheap, like $100 credit voucher goes for less than $5, etc. They are apparently obtained for free when buying some service/product or something.

I want to buy these vouchers and I will pay in Bitcoin.
They have to be much cheaper than their face value.

PM me, don't post here.
Thanks.

I'll let you know if I can't find anyone doing this for cheaper.

I have list of ~300-310 music artists in txt. You have to go to their last.fm page and find all top 10 most listened songs of their. (Top 10 songs are very convinirntly listed in the artist pages, you don't have to look much)

Then you have to download these 10 songs. These can only be mp3 and be of quality equal or higher than 192kbps. (It can be 128kbps if you download them from YouTube as last resort).

When it comes to finding songs you can torrent the Discography of the artist and choose only the top 10 songs to download. (If you use uTorrent you have ability to choose only the files you want to download from the whole torrent when you add the torrent. You have to pick only 10 MP3s from the torrent by ticking the box next to them. It's not hard at all).

These artists should be easy to find. If you can't find them anywhere then you can rip their mp3 from YouTube videos. (Use something like http://www.youtube-mp3.org/ )
You can use YouTube most viewed sorting instead of last.fm for these.

Each artist should get it's own folder (folder name is the name of the artist) and folder should contain mp3s with song's name as a filename. (No album folders or anything of such, only mp3s). Filename should be properly written and first letter capitalized. Filename can only be the specific song's name, nothing else.

After you get all the MP3s you have to let me download it. You can either host it as torrent, host it in HTTP or FTP, or anywhere else as long as I can download it at speeds of 4Mbits (500Kbytes+) or higher.
You have to ZIP or RAR these MP3s to single compressed file and host it like that.

I imagine that this task can be accomplished in 5 hours if you are efficient with your time.

Paying $50 BTC. PM me.
I will not go first. I will not pay unless your files meet my specifications specified above. If you get something like folders, filenames, quality, file formats, artists, songs wrong then I will ask you to fix them and I will NOT pay you until you fix it all.

I'll hire you later again if you do a good job and pay you much higher rates.

Free artists only, nothing illegal here.
