Day trading is a really difficult job to do due to the fact that  you must have to make an analysis day by day. In my opinion, you should go for a semi long term because not all the times your asset will fluctuate even in crypto. Crypto is somehow better at day trading due to a high rate of volatility so if you are into day trading then go for crypto. Regarding to your loss, just let it happen because this will be learning from you. Loss is the perfect lesson you will learn, you'll gain experience then you will able to handle it in no time.
