Consider this situation. I generate an electrum wallet. So electrum generates multiple address's from the same seed. That means all the address are somehow connected.
So if i sign a message say "This is to be signed" with Address 1 and sign the same message "This is to be signed" with Address 2 in electrum wallet and post both the signature online. Then will someone be able to recover my private key of any of the address? Please need some explanation here? I am worried and confused if we sign the same message from 2 two different address of same seed and then can the private key or seed be recovered from both signatures?

So i have decided i will start trading with 2BTC first. I have read many people suggesting me to day trade and earn some good profit daily.

where to learn the basics? some good books?
how much profit can i expect daily in the beginning?
How to avoid major loss?
is there any professional traders that allow to follow their trades and they charge some fees for it?
Waiting for your answers

Provided i have funds - 60BTC and no knowledge regarding business and i am not a designer but i want to start my own crypto business. Where can i start? Where can i find and hire team for myself like designers/developers etc to start my business? I know good team can help the business grow but bad team can ruin everything so what are the things to look for before starting a business? Where to get the business partners with good ideas and genuine team? Where would you start from if you are in my situation. Please share your opinions in this thread  

A simple question, If i buy 1000 DASH with Bitcoin and and run a masternode, i will generate passive income. My question is will the end result after 1 year (initial deposit + income) will be greater than if i decide to HODL bitcoin and don't run a masternode ?
I want to earn passive income but it has a risk right? What if DASH price falls after one year and bitcoin price keeps increasing,that can happen? or Bitcoin and DASH price directly proportional in long term?

Suppose you earned 60BTC by working hard for 5 years and one day you decide now you don't want to work then what would you do with that amount?
How would you invest that amount? What will you do? Hold it dreaming the price will rise? Sell it and invest the fiat? or start a business? or retire? Any ideas?
