I am full time crypto trader or a bounty hunter. Yes I believe in cryptos but in the present market scenario leaving a job is not advisable as you already watching whole market is very messy nobody knows market will go to which direction in coming days. As a trader or bounty hunter I earned a lot of money last year in the month of Nov-Dec 2017 but after that I am also struggling but anyhow I manage to meet my all expenses from cryptos earning and I am quite positive for crypto currencies good future so I am continuing it. Its not a one day or one month process to get success in crypto world. You need to give proper time for learning with all basic understandings of market if you want to make your good future.
