I always learn in trading must hold some coins that gettinh for a big dump to recover how much funds loss from you but i accept that and taking a break this time to avoid lossing more money.
Day trading is not a simple technique so we learn more about short term and mid term trading in crypto it will be good to improve the day trading skills. But your suggestion is totally matching from long term investment so I recommend buy Bitcoin in this bearish market. Because total market is suddenly moving to backward so we should buy more BTC in this dip.
