Still options are so expensive in Etheropt exchange, I'm waiting for better pricing. And some expirations are so close, I like longer expirations which means I will have more time to make profits and apply proper hedging strategies (risk management) on my existing positions.
Earning a living with Bitcoin is possible but I do not think that it is possible for everyone because you will need to handle in allot of them.
You will have to invest allot of money if you want to be able to to that.
yes mate if you really looking to earn to make a living you also needed to have big starting capital since you will not always earn big unless you have good deep understanding from the project you are supporting with, a lots of things to consider but very possible me i'm doing it by now because i got good entry coming from an ico coin which deliver big success i got 3btc to start and for me it can make some good earnings from time to time.
