I am currently transitioning to sustaining myself as a full time cryptocurrency trader. It is definitely not for everyone, and extremely risky to say the least, but it fits my personality and one of the very few possibilities of earning one’s living without any human interaction. It’s just you and the market.
My risk tolerance is very low, so I focus mostly on automated market making and microstructure trading. It is more like reversing other people’s strategies and designing my own to profit from them.
Which, by the way, is a full time job, you cannot just design some good algorithm and sit back while it earns you money. It is not this easy. :(
