I'm actually new to this industry and i want to earn some money without putting some in the line(A.K.A investing) and i doubt myself that i could actually know how to manage my coins is there any way to earn money that would kick start me in this industry?
I don't know what you mean by earning even if you don't invest. No matter how you think about it, if you say about money and earning, then you should put something that is worth your earnings. There is no easy way to earn money in a legit way, so you should invest like money, time or effort to earn something you want.
you can get income other than investment and and hold altcoin you can get income by buying and selling because this time you can do the buying and selling then from that investment and hold altcoin there are still many ways to earn income
