someone please tell me how to receive BTC?
the best place to start is
http://www.bitcoin.org, this will gt you started. if you want to skip th learning stage tonight and just get onto playing with penny amounts right now then start with a basic wallet such as blockchain.info just to get into action instantly.
sign up to
https://blockchain.info/wallet/newonce inside you will see "this is your bitcoin address" and a bit long jumble of characters. this jumble of characters is your bitcoin address, more specifically the public part that you are free to tell and show people.
next you can find people willing to sell you bitcoins on places like localbitcoins.com.
you can do jobs, EG going to jobs listing websites and offer any skill you have and ask them to pay you bitcoins to your bitcoin address
and lastly you can google 'bitcoin faucets' to get a small amount (alot less then 1cent) but atleast it will get you started to learn how to use bitcoins.
there are many bitcoin video's and introduction 'walk through guides' and if ever unsure use the search function of google and this forum.
once you start playing around with more then penny/cent amounts of bitcoin and begin to want to be secure. you will want to download a legitimate client wallet that sits on your computer instead of the internet. so refer to bitcoin.org for details
although the community is a helpful lot, you will have to understand that most people do not have the time and patience to explain every little detail about the whole last 5 years of services and history, and hand it to you on a platter for free in a small timeframe. it WILL take you time to learn it all, so be patient and try to learn the bits that will mean most to you, rather then trying to beg people to teach you everything.
have fun, welcome to the ecosystem where YOU own your wealth, and its not on loan to you by others or meant to be secured by others. and the main 3 lessons i can teach you now is
1. if you dont know the people you are trading with, they have no reputation and you cant physically slap them with a wet fish if they steal from you. dont get involved in the first place with them.
2. trust is everything as the funds cannot be reversed later
3. dont risk more then your willing to lose on any third party, only put pocketmoney/daily spend amounts on website wallets and handing to unknown strangers.(imagine with each transaction as if it was a suitcase of bank notes would you send it to that person/business based on their rep)
