Insane year indeed. The problem I get and what bugs me most is deciding the amount I should convert to fiat from the profit. It's easy to say HODL or leave it all there but fiat is still needed in a day to day basis, wish I could leave all the profits sitting there though.
Investing in crypto does not mean you have to invest everything in your wallet. A certain portion of your monthly or daily income should only be considered in your investment and most of your income should still go for your day by day expenses. You can't eat altcoins, so you have to secure some fiat to buy the things you need.
