wow...1-2 btc for a Legendary acc
how long time will it take to become Legendary?
coz i really can't understand the calculation of activity
read the meta section on ranks:
https://bitcointalk.org/index.php?topic=178608.0and i say, you already have an account with 14 account, hang around and built that up yourself. and if you want to buy an account you can but a full or Sr. member which are cheeper.
and for cloudmining i suggest you read this topic:
https://bitcointalk.org/index.php?topic=878387.msg9697654#msg9697654 you'll get good information there.
and if you are interested in mining so much, you can look into mining altcoins and selling them for bitcoin.
