For me 30% or more gain is still possible in everyday trading, especially if you choose new cryptocurrency which has a lot of supporters.
That's everyday man? Are you sure about that? you must be very good to earn that percentage on a daily basis, I call it impossible. Sorry...
Only Ponzi projects can guarantee daily gains and no one talks about the losses of the trading on a daily basis. It is possible but the question is to show us a proven track record for at least 6 months. Day trading can be precise in the theory but it doesn't work in the real live market because of the uncertainty.
