domain BitcoinMining.in, LoanOnline.co

[1domain]

Hello friends!

I am a newbie trying my hands on selling domain names, have just sold my first domain name at Godaddy auctions for $200. I am trying to learn and not rushing into buying lots of domains at the moment.

I will appreciate if you guys can kindly appraise my following domain names, this will be a great help for me to understand and make right choices while buying domains in future.

I know it is advisable for me to stick to .com. Most of my domains are .coms only, however it is difficult to find really good .coms. I have a thinking that following domains are good because of the keywords they have, please share your thoughts.

1. BitcoinMining.in - 'Bitcoin Mining' is top keyword. It attracts 201,000 monthly searches and stands second just after "Bitcoins" in Adwords.
2. DiamondJewellery.biz
3. eRobot.co
4. GoldJewellery.info
5. LoanSale.net
6. LoanOnline.co

Thank you very much for help and guidance.

Any thoughts, anyone?
Can .in domains be of any interest to international users or are they strictly limited to Indian users only?

Thanks
