As kinda the opposite to the HODL approach I've set up a fun challenge for 2018 to see how much I could make with only £20/ $20 seed in 2018. I've written about it here if you'd be up for joining the challenge? I get the potential profits aren't as big but it could be a low risk and fun way for people to get into Crypto.

Good luck
