Yes do some profits. Normally I am making it invest again on something worth investing. Like some I earned from an airdrop, I put that money into work again to earn another potential gain. Right now theres plenty of choices and option you just need to make sure its really a good one to use that money. Yes using profit for another potential profit is quite an adventure, its like a fulfillment.
Using the percentage of profits in another business is quite profitable. If you get the profit and do not invest it again then you will spend it and will remain empty handed so I think we should not stop the investment process once we get profit.
If you are in will to use half percentage of profit for investment and half not to invest then it is also fine but to cease investment means that you are again accepting your previous status and don't want to move forward.
