This is a very Tricky question to answer as there are several factors that are in Play when considering of you can Live of your Steemit Income. I am going to point out the two important factors in this Scenario.
First Point
Are you making Good Posts and is your Post earning some good traction when it comes to Payouts. This is an important Point as without a certain Amount of Payouts you can't Live of Steemit no matter where you are.
Second Point
The Place you are staying plays a huge part in all this. For example the Living cost in America is very high compared to the Living Costs in any Third World Countries. So your Geographical Location plays a huge part too.
Now all that being said my Personal opinion is not to take Steemit as a Source of Income for your Daily expenses. You may use the Money you get from Steemit for savings or other stuffs but do not try to Live off your Steemit Payouts as in a Cryptocurrency Market it could go down for more than 2-3 Months.
