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.
It is a hard to thing try and make a living out of cryptocurrencies only because that means that you will have to handle in allot of them to make enough money to be able to pay for everything that you need to pay.
For me it would not be possible that is why I use it as an secondary income.
Yes making a living out of crypto trading is very risky.One should not take it up as full time job.As a part time it is good additional option of income but only if you know how to trade
