Reject your past mistakes, Do everything possible to reject those things that make you not to maximize income, may be you use to buy crypto when the price is high already as a newbie, you can change from that attitude if you want to maximize income from crypto in this new year.
Avoiding FOMO. Read as much as you can.. knowledge is so potent, one of the strongest weapons against losses. Additionally, ask questions when you find something confusing and you need answers. Even if it sounds stupid, there will be someone who is patient enough to provide you with answers. I have had experience with it. Lastly, of you don't know what to do just HODL. You will not lose any crypto by hodling.
